Turbulence and Chemical Sensors in Slurry Flows – With support from NSF and the DuPont Stine Haskell Research Center, a four year research program into chemical sensor measurements in batch reactor slurry flows was conducted. The effects of turbulent flow behavior on the application of NIR optical sensors to measurements in horizontal and vertical pipe flows was examined through CFD. This research was performed with collaborators at the University of Tennessee, East Carolina University, and the DuPont Stine Haskell Research Center.
Automotive Air Filtration – With the support of Purolator Products, Inc. and the Oklahoma Center for the Advancement of Science and Technology in a seven year program, the role of inlet flow distributions upon automotive air filter performance has been investigated experimentally. The knowledge gained has been applied to the computational design of filter housings with desired flow distributions. Experiments using flow visualization and laser Doppler anemometer velocity measurements have documented the flow fields in laboratory test housings and vehicle housings with clean and dust-loaded filters. Fibrous filter theory has been applied to predict the effects of measured flow distributions upon initial, clean filter efficiency. Computational fluid dynamics has been applied to determine the local flow distributions between filter pleats and combined with computational optimization methods to design vehicle housings with specified filter velocity distributions.
Micro Flows and Micro Filtration - Lattice Boltzmann techniques are being applied to computations of micro channel and micro filter flows, extending filtration research to micro scale applications.
Fundamental Fluid Dynamics – Fundamental computational fluid dynamics has been applied to the problem of a channel flow separating over a backward-facing step with and without a downstream section of porous media modeling a filter. The effects of the porous medium on boundary layer separation and reattachment have been examined. Laser Doppler anemometer measurements of mean velocity profiles and turbulent flow fluctuations have been performed to validate the computational results. Turbulent boundary layers over moving walls have been studied in experiments using hot wire and laser Doppler anemometry and laser sheet flow visualizations. In research performed at NASA Langley Research Center, hot wire anemometer probe calibration relations have been investigated for probes operating into the free molecule flow regime in very low density wind tunnel tests. Changes in piezoelectric flow control actuator performance with local density also were investigated at Langley for a range of densities corresponding to the altitude range for aircraft operations. Experiments were performed for no flow and Mach 0.1 and 0.2 boundary layer flows.
Aeroacoustics – The aeroacoustic and fluid dynamic behavior of bluff body vortex shedding and separated shear layers flowing over open cavities have been investigated experimentally for applications in automotive wind noise diagnosis and reduction and aircraft noise reduction.
Dr. Chambers has broad experience teaching and conducting research in fluid dynamics. This research has been performed in academia, industry, and national laboratories and includes subjects that range from basic research on turbulent flow to applied research on industrial topics. His specialty is turbulent flow, with particular expertise in experimentation, flow field diagnostics, flow control, and acoustic-turbulent interactions. He has considerable experience with hot wire anemometry, laser Doppler anemometry (LDA), turbulent and acoustic signal processing and analysis, and visualization techniques for air and liquid flows. His experience encompasses both free and wall-bounded shear flows. He has served four years as an Associate Editor of the AIAA Journal, handling papers generally concerned with turbulent flows. His dissertation research involved acoustically enhanced development of turbulent jets. At Los Alamos National Laboratory, he investigated turbulent structure and relaminarization in turbulent duct flows subjected to flow acceleration. At Lockheed, he served as principal investigator for internally funded and contract research on projects that addressed various problems of boundary layer transition, skin friction drag reduction and shear flow control, thrust vectoring, analytical and experimental aspects of ice particle interaction with gas dynamic shocks, and vortex-shedding aerodynamic noise of automobiles. He also provided project support on subjects that included the control of flow and acoustic resonance of open cavities (windows for an aircraft-mounted optical radar), hypersonic test facility renovation and instrumentation, boundary layer separation control, and the far field acoustics of the Propfan Test Assessment aircraft. A patent disclosure on the generation of micron-sized ice particles resulted from the effort on the interaction of ice particles with shocks. With the support of the Oklahoma State University Web Handling Research Center, he served as principal investigator for research on the prediction and control of the air films associated with moving plastic or paper webs and their support rollers. This work involved moving wall boundary layers and the tribology of foil bearings. With the support of Purolator Products, Inc. and the Oklahoma Center for the Advancement of Science and Technology, he served as principal investigator conducting research on the effects of inlet flow fields on automotive air filter performance in laboratory test housings and vehicular housings. This work involved flow visualizations of complex separating flow fields, LDA flow field measurements, application of fibrous filter theory to measured velocity distributions, and the application of computational fluid dynamics to predictions of filter housing flow fields and the smaller scale flow distributions through filter pleats. As a NASA/ASEE Summer Faculty Fellow at NASA Langley Research Center in 1999 and 2000, he studied very low density hot wire anemometer calibration in support of the Mars Flyer program and density effects on the performance of synthetic jet flow control actuators. He also directed research on the propagation of pulsed flow in ducts in support of applications of pulsed blowing to circulation control wings. He has directed LBM computations of micro channel and micro filter flows. He was PI in a four year NSF-funded research program into chemical sensor measurements in batch reactor slurry flows. This research was conducted with collaborators at the University of Tennessee, East Carolina University, and the DuPont Stine Haskell Research Center. He has administered four two-year R&D Intern programs at Mercury Mercruiser in Stillwater funded by the Oklahoma Center for the Advancement of Science and Technology with matching funds from Mercury. Thirty-one OSU undergraduate engineering students participated in the program. His teaching experience has included fluid mechanics, heat transfer, thermodynamics, and instrumentation and measurements. Recently, he taught the MAE 3223 Thermodynamics II, MAE 3233 Heat Transfer, and MAE 4273 Experimental Fluid Dynamics undergraduate courses, and the MAE 5233 Viscous Fluid Dynamics and MAE 6233 Turbulent Fluid Dynamics graduate courses. In MAE 6233, he covered both a traditional introduction to turbulent flow and a survey of the development of turbulence models for computational fluid dynamics. He is a Registered Professional Engineer in the states of Georgia and Oklahoma.
