Modeling of Heat Flux Distortion Around Heat Flux Sensors

Source

The effect of a heat flux sensor on the heat transfer in the material surrounding the sensor has been studied in detail, and a steady-state finite difference computer model has been written to predict the ratio of the heat flux through the sensor to the undisturbed flux in the material surrounding the sensor, qs/qm, as a function of the ratio of the thermal conductivity of the sensor to that of the surrounding material, , as a function of the ratio of the thermal conductivity of the sensor to that of the surrounding material, ks/km, and the geometry of the situation. The results of the program show that , and the geometry of the situation. The results of the program show that qs/qm is a strong function of is a strong function of ks/km, varying from 0.37 to 1.31 as , varying from 0.37 to 1.31 as ks/km varies from 0.1 (concrete) to 10.0 (polystyrene) for a typical sensor in the center of surroundings 25.4 mm thick.
