Abstract
A method for the determination of the heat transfer coefficient on a heat transferring surface, including the steps of arranging a layer for measuring the surface temperature and heat flux on the heat transferring surface so that the layer can change the original temperature and heat flux to a negligible extent only, providing for the slight and properly slow changeability of the surface heat flux density within a cycle time which is by several orders of magnitude longer than the time constants of the heat flux measuring layer and of the heat transferring boundary layer, by using a supplementary heating element and performing a practically unlimited number of measuring cycles, using the steps of deflecting the surface heat flux density and temperature relative to the condition in which no measurement takes place. The time-functions of the changes of the surface temperature .DELTA.T and of the surface heat flux density .DELTA.q are determined, and the heat transfer coefficient is defined as the approximate limit value H of the quotients .DELTA.q/.DELTA.T corresponding to the zero surface heat flux density or temperature deflection.
