The paper is intended to present both experimental and numerical approaches for estimating the heat exchange per thermal radiation towards the walls of lab–scale paraffin–based thrust chambers. Two firing tests of a lab–scale gaseous–oxygen/paraffin–wax hybrid rocket engine have been performed to apply such methods. In particular, the radiative wall heat flux has been evaluated by both spectroscopic measurements and discrete transfer method computations. Details of such approaches are given together with results achieved and suggestions for future improvements.

Abstract

In particular, the radiative wall heat flux has been evaluated by both spectroscopic measurements and discrete transfer method computations.
