A new calculation method is presented for heat transfer in coupled convectiveconductive fluidwall systems under periodical intensity oscillations in fluidflow. It is demonstrated that the true steadystate mean value of the heattransfer coefficient has to be multiplied by a newly defined coupling factor.This correction factor is always smaller than one and depends on the couplingparameters Biot number Fourier number as well as dimensionless geometry andoscillation parameters. For characteristic periodic heat transfer problemsanalytical solutions are given for the coupling factor. To facilitateengineering application the monograph also presents the analytical results inaccompanying tables and diagrams. TOC1. Introduction. 2. Construction of ageneral solution of the problem. 3.
