The present book considers the generalization of the universal method of investigation of the periodic conjugate problem of heat transfer to the case of mass transfer through the interphase. We describe the effect of periodic pulsations of hydrodynamic parameters on the averaged mass transfer through the interphase boundary between moving media. In this way, we obtain a generalization of the classical analogy between heat and mass transfer. The general problem of averaging of parameters of unsteady mass transfer (concentration and mass flux on a mass transfer surface, boundary conditions, mass transfer coefficient) is also considered. We introduce the concepts of the "true" and "effective" mass transfer coefficients and of the "averaging factor". We obtain analytical solutions for the main variants of periodic variation of the true mass transfer coefficient. The averaging factor is evaluated in analytical form (sums of infinite continued fractions and infinite series), and in the form of graphs and nomograms. Asymptotic formulas of the solutions are obtained. The book will be useful for researchers and graduate students engaged in research on unsteady convective mass transfer.

A new calculation method is presented for heat transfer in coupled convective-conductive fluid-wall systems under periodical intensity oscillations in fluid flow. It is demonstrated that the true steady-state mean value of the heat transfer coefficient has to be multiplied by a newly defined coupling factor. This correction factor is always smaller than one and depends on the coupling parameters Biot number, Fourier number as well as dimensionless geometry and oscillation parameters. For characteristic periodic heat transfer problems, analytical solutions are given for the coupling factor. To facilitate engineering application, the monograph also presents the analytical results in accompanying tables and diagrams.

This book presents the theory of periodic conjugate heat transfer in a detailed way. The effects of thermophysical properties and geometry of a solid body on the commonly used and experimentally determined heat transfer coefficient are analytically presented from a general point of view. The main objective of the book is a simplified description of the interaction between a solid body and a fluid as a boundary value problem of the heat conduction equation for the solid body. At the body surface, the true heat transfer coefficient is composed of two parts: the true mean value resulting from the solution of the steady state heat transfer problem and a periodically variable part, the periodic time and length to describe the oscillatory hydrodynamic effects. The second edition is extended by (i) the analysis of stability boundaries in helium flow at supercritical conditions in a heated channel with respect to the interaction between a solid body and a fluid; (ii) a periodic model and a method of heat transfer simulation in a fluid at supercritical pressure and (iii) a periodic quantum-mechanical model for homogeneous vapor nucleation in a fluid with respect to nanoscale effects.

This book provides a detailed yet comprehensive presentation of the theory of periodic conjugate heat transfer. It contains an analytical approach to the effects of thermophysical and geometrical properties of a solid body on the experimentally determined heat transfer coefficient. The main objective of the book is a simplified description of the interaction between a solid body and a fluid as a boundary value problem of the heat conduction equation.This third and extended edition covers Wall's thermal effect on Landau stability, gas bubbles pulsations in fluids, and also the interplay between periodic conjugate heat transfer and non-Fourier heat conduction. The target audience primarily comprises research experts in the field of thermodynamics and fluid dynamics, but the book may also be beneficial for graduate students in engineering.
