Abstract: The structure and measurement principle of slugtype heat flux sensor are introduced. For a series of factors affecting the measurement results, such as the shape and size of the sensitive component of the sensor, the thermal conductivity and thermal capacitance of the heat insulation layer and the surface emissivity of the two materials Etc., the heat transfer simulation to various models is conducted by Fluent software and the affections of different factors to the measurement results are analyzed. It can provide a reference and guidance for the development of the heat flux sensors.
Key words: Heat flux sensor, Software, Numerical simulation
