Abstract
This study has investigated numerically the interaction of cryogenic hydrogen jet with heated hydrogen cross flow under supercritical pressures relevant to a mixer component in liquid rocket engines. The mixer is considered to be a key component for achieving high reliability of LE-X engine, where an expander bleed cycle is adopted. A two-dimensional simulation of hydrogen jet in cross flow under a supercritical pressure is first performed to explore mixing characteristics in a wide range of injection conditions. Effects of injection temperature and therefore momentum flux ratio on the hydrogen jet in cross flow are comprehensively investigated. A high-order numerical method for the Navier-Stokes equations with a real-fluid equation of state is used for resolving highly unsteady flow fields with large density gradients.
