Therefore, sensors to measure heat flux usually must be mounted onto a material that provides a good heat sink so that the energy flow is not impeded. In addition, it was shown that by adjusting how the temperatures used in the HHF method were weighted, the hybrid method could be specifically
Heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. In SI its units are watts per square metre (W/m2). It has both a direction and a magnitude, and so it is a vector quantity.
Heat flux by the convection process is directly proportional to the temperature difference between solid, liquid, or gaseous media participating in heat transfer. We can measure heat flux mainly by the following two methods: The most common but often impractical, the method is by measuring
