Abstract: Abstract The generally adopted strategy to investigate the flow on a pump-jet propulsor (PJP) is in model scale, but the flow is often overestimated as full turbulence in numerical prediction. The effects of transition modeling… read more here.

Abstract: Inspired by the silent gliding feather of owl wings, the trailing edge of the duct of a pump-jet propulsor was designed with a similar serrated structure in order to reduce noise generation. Two distinct serrated… read more here.

DOI: 10.1063/5.0196459
Abstract: For a pre-swirl pump-jet propulsor (PJP), the stator inevitably induces the problem of rotor–stator interaction (RSI). In this paper, the mechanism of RSI in a PJP is analyzed through dynamic mode decomposition (DMD). The coherent… read more here.
