Injector-Wall Interactions in Gas-Centered Swirl Coaxial Injectors

Abstract

Rocket engines often rely on tailoring wall elements to provide a fuel-rich wall environment or to cool the wall or both. Due to their importance in protecting the wall, it is imperative that the behavior of these elements is understood. The nearby wall may alter the performance from that of a single, isolated element. Most experiments are not designed to elucidate these effects; either single, isolated elements are examined, or arrays with walls are generally only examined during hot-fire testing. These tests focus on impact of a wall on the spray. The general character, attachment point, spread of the spray and stability are all considered.
