Inflow and interaction of cofluent starting jets into a plenum with minimal losses (C02*)

• Subject Area: Fluid Mechanics
• Term: from 2016 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 200291049

At the exit of the detonation pipe into the plenum we expect substantial losses such that efficiency of the overall engine substantially deteriorates, if the exit is not designed diligently. Additionally closed by pipes will interfere and lead to problems for the refilling as well as to instabilities in the plenum. In this project we want to understand and quantify the losses due to shocks. By data assimilation and Schlierentechniques using a high-speed camera we further want to develop to measure these losses in situ. The mutual interaction of the jets and with the plenum walls will be investigated numerically.
