A MINIATURE SENSOR FOR MEASURING HEAT-TRANSFER RATES IN ENGINES

A device for measuring steady-state heat-transfer rates in a solid was designed after an extensive heat-transfer analysis. Subsequent experimentation and development has led to an accurate miniature sensor which can be installed directly into a parent material with little thermal disturbance. An analytical model of the sensor, installed in the combustion chamber wall of an engine, predicted this disturbance error to be 3% or less over a wide range of parent material properties and engine operating conditions. Experimentation at four heat-transfer rates confirmed this predicted performance. /SAE/
