Gas Dynamics Imaging Laboratory

Ben, Jose, Professor Gamba, Alex, Kohei, Riley, Rahul – Fall 2022

Our research focuses on understanding fundamental problems relevant to advanced aerospace propulsion concepts. Some areas of research are predicting performance in rotating detonation engine, shock-boundary layer interactions in an isolator, thermoacoustic instabilities and emissions in a model gas-turbine combustor, and supersonic combustion / mixing. Our group utilizes experimental techniques such as laser-based diagnostics (spectroscopy, OH PLIF), schlieren imaging, high speed imaging, and OH* chemiluminescence to investigate the physics of such devices. Below is a gallery of some of our RDEs, experimental set ups and example post processed data.
