Processes of heat transfer with periodically varying 
intensity on the surface of heated bodies of three typical geometries 
(plate, cylinder, sphere) are considered. The true heat transfer coefficient, 
which varies in time by the law of a periodic step function having 
two free parameters  - amplitude and asymmetry, is specified 
on the heat transfer surface. Resultant relations are obtained for 
calculating the experimental heat transfer coefficient, which is the 
quantity measured in a traditional heat transfer experiment and used 
in applied calculations.
