Heat Flux Measurements in High Enthalpy Flows

Abstract

This document describes the fundamentals of heat transfer measurement techniques in high enthalpy flows. After description of basic relations for the stagnation point heat flux rate to a spherical surface in a high enthalpy flow field, different heat flux measurement techniques are discussed. Attention is paid to design aspects, mathematical model for the heat flux rate evaluation and application limits of each sensor type, in order to provide a useful and practical script for the reader with respect to the choice of an adequate sensor type for different requirements. Sensor calibration and comparative measurements using different heat flux sensors in the arc heated facility LBK are described in the last two chapters.
