Computations of Supersonic Lateral Jets

초록

Lateral jets used in hit-to-kill vehicles induce complex jet interactions with external supersonic flows. It is of paramount importance to analyze these jet interactions accurately in order to predict the missile performance. In this paper, we numerically analyzed the jet interaction on a supersonic generic missile by using an in-house CFD solver, MSAPv. Various numerical flux schemes were used to examine the complex flow field. The results at three conditions were computed and compared to the experimental results as well as each other. In addition, the complexity of the interacting flow was investigated using the behavior of vortical flow structure around the lateral jet.
