Abstract: Electric ducted fan has newly emerged as the most compact type of propulsion fan for flying cars, because of its flexible configuration arrangement, low noise level and high safety level operation. Typically, an electric ...

Abstract: Aerodynamic stability enhancement is crucial for the stable operation of supercritical carbon dioxide (SCO2) centrifugal compressors. This paper investigates the mechanism of aerodynamic instability of shrouded SCO2 ...

Abstract: The performance of membrane humidifier (MH) and enthalpy wheel humidifier (EWH) for a large power proton exchange membrane fuel cell (PEMFC) system is compared using simulations and experiments. ...

Abstract: The compressor is operated at unsteady exit conditions in many scenarios such as the instability of combustion in gas turbine and denotation engine. The aerodynamic stability of the compressor is inevitably influenced by ...
