Heat flux is defined as the quantity of heat transfer per unit surface area per unit time. Heat flux to or from a surface can be inferred from temperature-time measurements at the surface or within the body or can be measured directly, using heat flux meters. In the first approach the flux or heat transfer coefficient is determined from the solution of the steady-state or transient inverse heat conduction problem. The operation of the heat flux meters is based on the simple relations between the heat flux and temperature difference between two points located inside the sensor or at its surfaces. Also, the variation of sensor temperature with time is used to determine heat flux to the meter. Uncertainties in the determined heat flux and heat transfer coefficient can be estimated using the variance propagation rule developed by Gauss.
