EXPERIMENTAL AND NUMERICAL STUDY OF SUPERSONIC FILM COOLING

Abstract

An experimental study performed at ONERA to simulate film cooling in a rocket engine wil be presented. Motivations will first be reminded and the experiment design will be brifly described. In the experiment, two injector heights, cold and ambient temperature films as well as matched, under- and overexpanded films have been investigated. The mixing process has been documented by measuring the Mach number and temperature profiles. In addition, wall pressure and temperature as well as heat transfer coefficients have been measured. Some of these data will first be used to explain the physics of supersonic film cooling and its main advantages. CFD predictions of the flow will then be discussed, to highlight the requirements on turbulence models to be able to reproduce the flow physics.
