Abstract

In the frame of future changes in propellant combinations and ignition methods, like e.g. laser ignition, for RCS (Reaction and Control System), OMS (Orbital and Manoeuvring System) and cryogenic upper stage engines, fluid flow structures and injection phenomena is the so-called flash evaporation, which is a sudden evaporation of a super-heated liquid. A liquid becomes superheated if it is injected into an atmosphere with a pressure below its saturation pressure at injection temperature. TP-B4 focusses on the experimental investigation of superheated LOX (liquid oxgen) injected into a near vacuum atmosphere. Hence a new test bench with a specific cryogenic injection system is developed. This test bench will permit a systematical and detailed characterisation of LOX flash evaporation as a function of the injection conditions and geometries.
