Research Interests   return to top

Research in fluid mechanics and heat transfer has been conducted with graduate students and colleagues at the Air Force Research Laboratory (Phillips site), Sandia National Laboratories, and NASA-Ames Research Center, as well as the UNM Departments of Biology and Center for High-Technology Materials. This research has been concentrated on turbulence, for the purposes of modeling for computational fluid dynamics (CFD), experimental studies, as well as using the results of direct numerical simulation of turbulent flow to study turbulence physics.

1) Chemical Laser Mixing. This research has been supported by the Air Force Research Laboratory (AFRL), the Missile Defense Agency, and DARPA, though the DOD's Joint Technology Office for High Energy Lasers. Professor Peter Vorobieff of UNM Mechanical Engineering and Drs. Gordon Hager, Charles Wisniewski, Jerry Manke, Kevin Hewitt, and Tim Madden--all of AFRL/DELC--are my collaborators on these projects.

2) Flow Control Using Deformable Airfoil Surfaces and Oscillatory Blowing. A NASA Faculty Award for Research and the NASA Center For Intelligent System Engineering provided support for predictions of turbulent flow on airfoils with various flow control technologies and associated experiments. Dr. Kambiz Salari, of Lawrence Levermore National Laboratory, is my collaborator on these projects.

3) Aero-optical degradation by turbulent fluctuations in shear layers. click here for sample images
In research sponsored by the Air Force Office of Scientific Research and the Air Force Research Laboratory--Phillips Research Site, the effect of coherent turbulent structure upon propagation of an optical beam through a turbulent shear layer has been studied. A practical turbulence model to predict the degradation in beam quality was also developed by extending the concept of turbulent transport equations to the index-of-refraction fluctuations. The importance of coherent structure in turbulent shear layers was identified first by studying direct numerical simulations of a homogeneous shear flow. This may explain some anomalies observed in optical propagation through aircraft boundary layers. These studies suggest that the dominant effect of a turbulent shear flow upon optical propagation may be represented by a model which includes only the large fluctuations generated by the large-scale turbulence structure. A predictive model for scalar fluctuations in a turbulent channel flow was based on a nonlinear dynamical system model. The chaotic fluctuations produced by this model were compared with those predicted by direct numerical simulations from NASA-Ames. An experimental facility was built at the Phillips Laboratory to simultaneously measure optical and fluid dynamic properties of a heated turbulent jet. A dynamical model was constructed for this free shear flow. This work was done in collaboration with Prof. Rick Zadoks, of the University of Texas, El Paso, as well as Phillips Laboratory researchers including Dr. John Wissler, Dr. Lenore McMackin and Dr. Bruce Masson. This work has also included a careful examination of instrumentation used on airplanes to measure atmospheric turbulence which will have impact on the Air Force Airborne Laser Program.

4) Turbulence modeling in supersonic and hypersonic boundary layers. The extension of turbulence models developed for incompressible flows to high-speed flows typical of reentry vehicles and hypersonic vehicles was examined under the sponsorship of Sandia National Laboratories, Albuquerque, and General Dynamics, Fort Worth. With appropriate adjustments for the compressibility of the flow, simple algebraic turbulence models were found to reliably predict attached flows from Mach 3 to 9. Grid convergence studies were used to determine that accurate solutions could be obtained with a finely-spaced grid near the solid surface. The importance of the grid in obtaining accurate predictions of wall shear stress and heat transfer was clearly demonstrated. The most recent work was related to examining approximate analytical means to treat the near-wall region to relieve the grid requirements. The objective is to maintain a high degree of accuracy while significantly reducing the computation time.

5) Wind-blown transport of sediment and the sheltering effects of vegetation. In a collaborative study with Dr. Brad Musick from Biology, wind-tunnel and field models of aridland vegetation were used to determine the minimum plant cover needed to prevent erosion of soil by wind. Local effects in the wake of individual roughness elements which represent vegetation are hypothesized to have a significant influence on plant density and porosity required to protect the soil. In addition to solid roughness elements used in the wind tunnel models, porous elements which more closely model real plants have been used. The effect of porosity is not monotonic; slightly porous elements provide more protection than solid elements, but highly porous elements provide less protection than solid elements. This work, sponsored by NASA, is related to remote sensing applications in the Global Change Program.

6) Stratified thermal storage. In collaboration with Prof. M.W. Wildin, experimental and computational studies of stratified-liquid thermal storage tanks were made. This work included full-size and scale-model tanks in the Mechanical Engineering Building which are used to store chilled water for air conditioning needs. This work was sponsored by the Electric Power Research Institute (EPRI) to study electric load leveling and energy conservation. I supervised the design, construction and testing of the scale-model tanks in which flow visualization as well as flow and temperature measurements were made. The measurements were used to refine a numerical model of stratified thermal storage with tank walls with significant thermal capacity. Since the formation of the thermocline in the storage tank was determined to be quite important to performance, further experimental and numerical studies of thermocline formation were undertaken by two Ph.D. students; I assisted Prof. Wildin in advising and guiding these students. The results of the UNM studies were widely disseminated in EPRI and ASHRAE design guidelines.

7) Viscous flow between rotating disks. This work, sponsored by Sandia National Laboratories, has applications in turbomachinery or other equipment with rotating surfaces. At high flow rates (as opposed to lubrication applications), the turbulent flow is rotating and three-dimensional. Various turbulence models and numerical schemes were investigated.

8) Lubrication in float polishing. Prof. K. Jungling and Dr. Chris Kranenberg of the UNM Center for High-Technology Materials requested assistance in analyzing the fluid dynamics of float polishing of optical surfaces. This analysis led to the first understanding of the mechanism of load support employed in float polishing where the optical surfaces are rubbed against a lap with a surrounding viscous and abrasive slurry.

9) Heat Transfer This work was carried out during my graduate studies under the direction of Professors Darryl Metzger and Lee Florschuetz. The experiments consisted of careful measurements of local heat transfer under jet array impingement. This was applicable to gas turbine blade cooling.
