Code Validation of CFD Heat Transfer Models for Liquid Rocket Engine Combustion Devices

摘要

This paper reports on the development of a new heat transfer test rig for exploratory testing of new technologies for controlling chamber wall heat transfer. The design of the rig and its capabilities are described. A second objective of the test rig is to provide CFD validation data under conditions relevant to liquid rocket engine thrust chambers. The approach to validation that was adopted was to establish the minimum level of validation uncertainty that can be achieved for a fully-reacted, uniform flow. A method for characterizing the surface temperature and heat flux to the wall is described based on sensors embedded within the wall of the chamber.
