Muhammad Mustafa (PhD Student)


I was born in Pakistan and moved to NYC where I became a U.S. citizen and attended Forest Hills High School. At Stevens, I developed an interest in Fluid Mechanics and joined Dr. Parziale's group right after I completed my BS and MS. My research is in developing a non-intrusive velocimetry technique called Krypton Tagging Velocimetry (KTV) to study supersonic and hypersonic flows. This technique enables one and two dimensional velocity measurement in high-speed turbulent boundary layers and regions of shock-wave/boundary-layer interaction. In my free time I enjoy reading and watching movies.

Kryton tagging velocimetry

The Air Force requires non-intrusive velocimetry techniques for use in hypersonic test and evaluation facilities. The non-intrusive velocimetry techniques will be used to study flow fields of interest to the Department of Defense (DoD); examples include: high-speed boundary-layer transition, high-speed turbulent boundary layers, and shock-wave turbulent boundary-layer interaction. These investigations are intended to further the understanding of the fundamental flow physics that influence the behavior of large-scale test articles to aid in the development of concepts being considered for Conventional Prompt Global Strike. Krypton tagging velocimetry (KTV) is well suited for this purpose because of its versatility.

Shock-Wave/Boundary-Layer Interaction (SWBLI)

Shock-wave/boundary-layer (SWBLI) interaction is a rich fundamental fluid mechanics problem that has heating, drag, and structural implications. One example flow field is the compression-corner which could model the flow path of an air-breathing engine or the deflection of a control surface in high-speed flight. We've been able to use the KTV technique to make non-intrusive measurements of velocity in a Mach 3 shock-wave/turbulent boundary-layer interaction (below). With this effort in the AEDC Mach 3 Tunnel, we were able to measure the mean and fluctuating velocity profiles over several compression-corner angles. From this velocity data, analyzed the shear layer that develops near the root of the compression-corner and, using snapshot Proper Orthogonal Decomposition (POD), we were able to extract the most energetic structures in the SWBLI.

Novel technical approaches to thermo-chemical biomass conversion

Thermo-chemical biomass conversion by fast-pyrolysis to bio-oil, bio-char, and non-condensable gases is a part of an attractive path to an alternative energy source because of the upgrade in density and heating value. Reducing the cost of this process and increasing the quality of the bio-products are of interest. Current efforts are focused on working towards these goals.

Energy Capture and Emissions Reduction in Ammonium Nitrate Wastewater Treatment

Ammonium Nitrate Solution (ANSOL) is a byproduct of the fabrication of energetic materials and is being generated in substantial quantities at Army Ammunition Plants. The Holston Army Ammunition Plant (HSAAP) facility produces around 6 million lbs/year of ANSOL. Solutions of ANSOL are acidic and mainly composed of ammonium nitrate. Because of its corrosive and toxic characteristics, ANSOL results in significant handling and disposal costs. This situation will worsen in the near future as there is an expected 40% increase in ANSOL generation forecasted within the next few years. We are investigating an alternative to the current disposal methods; the literature suggests that with the right additive and operating conditions, ammonium nitrate can potentially be combusted to produce energy while minimizing hazardous emissions and residues. Essentially, we are treating the wastewater as a nitrogen-based fuel stream and performing thermal testing in a differential-scanning calorimeter (DSC) (below).

Fundamental interests in biomass conversion

Working towards characterizing phenomena at the gas/surface interface of biomass during fast pyrolysis is of interest. This is motivated by our need to further understand the heat and mass transfer processes. These efforts are intended to supplement the aforementioned technical efforts in terms of predictive science.

Novel approach to generation of hypervelocity flows

The expansion tube and tunnel (ET) have been developed as hypersonic ground-test facilities for approximately half a century. The appeal of an ET is the higher maximum reservoir mass specific enthalpy and reservoir pressure than in a reflected shock tunnel (RST). The expanded parameter space in an ET is due to the unsteady manner in which the test gas is processed. Successful operation of an expansion tube or tunnel is often hampered by excessive perturbations in the test gas; efforts to reduce these perturbations are critical. Significant improvement of the flow quality is possible with the vertical expansion tube (VET) relative to the conventional (horizontal) expansion tunnel (ET). The adverse effects from secondary diaphragm rupture in an expansion tunnel may be reduced or eliminated by orienting the tunnel vertically, matching the test gas pressure and the accelerator gas pressure, and initially separating the test gas from the accelerator gas by density stratification. Two benefits are: 1) the removal of the diaphragm particulates in the test gas after its rupture and 2) the elimination of the wave system that is a result of a real secondary diaphragm having a finite mass and thickness.

Focused laser differential interferometry

Advances in diagnostic development and electronics have allowed researchers to advance the state of the art in laminar-turbulent transition work. Only recently have there been measurements of the instability on a slender body within a hypersonic boundary layer in a thermo-chemically active environment. This was done with focused laser differential interferometry (FLDI), which is a non-intrusive optical technique that probes density fluctuation. The newfound tool have been used to characterize the noise environment in the large-scale shock tunnel T5. Preliminary work suggests that hypersonic instability phase speed measurement may also be possible with FLDI.

Prospective Students

Thank you for your interest in my research group and in Stevens. I receive a number of inquiries regarding the availability of research positions in my group, and unfortunately cannot always respond to these requests. However, I would like to post some comments on frequently asked questions regarding my group and research opportunities at Stevens.

Many graduate students (and faculty!) also greatly enjoy the location of the Stevens campus, which is situated in beautiful and vibrant Hoboken, New Jersey, 10 minutes from downtown New York City and easily accessible by all manner of public transportation.


Q: I am interested in working in your group; do you have research assistantships available?

A: I am always looking to add highly qualified, motivated, and hard-working students to my group! It would be premature to discuss possible financial support that may be available until a prospective student has applied and accepted by the Stevens Graduate School. In your Personal Statement, I strongly recommend indicating why you are interested in attending Stevens and why you are interested in working with my group. This will ensure that after your application has been reviewed and accepted by the Graduate Program Committee at Stevens that it will be forwarded to me.

Please note that Stevens has several additional mechanisms available to support US citizens and Permanent Residents interested in pursuing graduate studies at Stevens. Please contact me directly for more information regarding these programs.

Q: What are the requirements and test scores (TOEFL, GRE) that are required to apply to Stevens?

A: While Stevens does not have minimum GRE or TOEFL test scores needed to apply, your scores on these tests factor into decisions which are made regarding admission and financial support for graduate students (other factors include prior education, prior research experience, publication history, etc). The higher your scores, the more attractive your application will be to the Graduate Program Committee.

Q: I am interested in a post-doctoral position with your group. How can I apply for such a position?

A: I would recommend that you email me a complete CV (including a list of at least three references) and two representative publications which highlight your research work to date. I would also recommend a Personal Statement indicating why you are interested in my group, how you feel you will be able to contribute to my research group, and how a post-doctoral position with my group fits into your larger career goals. Be sure to comment on any previous experience you may have in writing research proposals. If you are an international scholar, it would also be beneficial to know of your availability to work in the US and when you would be available to start.

Q: I am interested in pursuing a Masters degree in Mechanical Engineering at Stevens. Are Research Assistantships or Teaching Assistants available for Masters students?

A: As a general rule of thumb, PhD students are more likely to be supported on RA or TA positions. However, outstanding Masters students with strong research experience will be considered for such support. In such cases, Masters students must pursue a 6 credit thesis option for the Masters degree. In the past such students typically work towards completing a PhD in a related topic/field at Stevens upon completion of the requirements for their Masters degree.

Q: How can I learn more about your research?

A: A general overview of the research activities of our group can be found on this page. In particular, I make a concerted effort to update the Publications section specifically so that potential graduate students can see our latest work. If you are interested in a research position with my group, a good first step is to be able to convince me that you have researched (e.g., read) at least some of the publications of my group.

Q: Do you accept part-time PhD students to work with your group?

A: Due to its proximity to a large number of military, government, and industrial R&D centers, Stevens has a rather large number of students who pursue their PhD degree part-time while working full-time. Successful part-time PhD students are often able to define a PhD project related to the students technical work responsibilities while also of interest to the faculty advisor. Several mechanisms at Stevens support part-time PhD studies (for example, the overwhelming majority of graduate courses are offered in the evenings, and some graduate courses are offered on-line, through a short-course format, or off-site). If you have confirmed that your employer would support you participating in such a program, please contact me directly for further discussion.

Q: I've been accepted to several PhD programs in Mechanical Engineering in the US. Why would you suggest that I enroll at Stevens?

A: First, congratulations on your fine achievement! I believe that you will find that the strengths of the PhD program at Stevens include having access to state of the art facilities and cutting-edge research opportunities in a vibrant small-school setting where many faculty (including myself) take great pride in offering personalized mentoring and advising to our graduate students. Further, I strongly believe that PhD students at Stevens in general, and my graduate students in particular, greatly benefit from close interactions and collaborations with students and faculty from other research groups both inside and outside the Mechanical Engineering Department.
