Numerical Study of Pipeline Distribution Effect on the Performance of Pasty Propellant Rocket Motor

Renjie Hu,
Weizong Wang

Abstract: This paper reports the numerical research on PPRM (pasty propellant rocket motor) through computational fluid dynamics simulation along with pipeline design comparison based on simulation results. The structure of PPRM includes feed pipelines, and the propellant is distributed in a cone shape when burnt steadily in the combustion chamber. As a result, the internal flow field presents strong 3-dimensional characteristics, which may lead to the flow instability. To accurately understand the combustion flow field… Show more
