Abstract: Provided in a compact system is a rapid response h-q-T sensor assembly, with associated processor and holding device, for measuring temperature, T, and heat flux, q, in a severe operating environment. From measured temperatures, T, and heat flux, q, a stagnation point recovery temperature, Tr, and a heat transfer coefficient, h, may be calculated using approximation algorithms loaded in the processor. The system approximates the ideal conditions in which Tr is derived from measuring a high temperature, i.e., a zero heat flux path to ground, i.e., q=0, r=∞ and a lower wall temperature measured along an infinite heat flux path, i.e, q=∞, r=0. Although ideal conditions are not able to be duplicated, appropriate positioning of heat flux indicators and temperature indicators in the surface of a thin film on the q-h-T sensor assembly, while allowing for very short duration sampling in a hostile environment, permits a viable approximation.

Abstract: A thin sensor for heat flux and temperature, designed for adhesive attachment to a surface, is manufactured on a flexible insulated metallic substrate. The sensor exhibits a combination of high sensitivity for heat flux and low resistance to the flow of heat. These characteristics enable it to measure heat flux at surface boundaries with improved accuracy over conventional heat flux transducers because the temperature drop produced by the sensor is very small. The response by the sensor to radiation, convection and conduction are equal. As such, the sensor can be calibrated in one mode of heat transfer and used for measurement in other modes. The high sensitivity of the sensor makes it ideal for measuring heat flow through insulating materials, and well adapted to instrumenting heat flow in buildings, detecting fires at an early stage, or remotely measuring the temperature of string and web products in industrial processing.
