Research activities in the Energy & Power Systems group consider supersonic flows, flows and heat transfer within air breathing engine components, heat transfer augmentation technologies, and micro-scale and millimeter-scale flows, including the effects of elastic turbulence, and micro-scale slip from rarefaction. Expertise and areas of application include: Supersonic Flow and Shock Wave Interaction Investigations Elastic Turbulence Investigations Double Wall Cooling Investigations Surface Roughness Effects on Impingement Array Surface Heat Transfer Internal Passage Heat Transfer Augmentation Methods and Associated Unsteady Flow Structural Characteristics Second Law Losses Around a Turbine Guide Vane Unsteady Milliscale Impingement Jets and Associated Vortices for Surface Heat Transfer Augmentation Dean Flow Dynamics and Cell Separations in Low-Aspect Ratio Spiral Microchannels Dr. Phillip Ligrani's faculty page Faculty Spotlight Dr. Phillip Ligrani Eminent Scholar in Propulsion and Professor of Mechanical & Aerospace Engineering For more information on energy & power systems at the Propulsion Research Center, please contact Dr. Ligrani.
