Research

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.

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.

Kryton molecular 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 molecular tagging velocimetry (KMTV) is well suited for this purpose because of its versatility.

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.
