SINOPSIS

In the present work there are suggested the method for a determination of internal heat transfer coefficient based on solving the inverse unsteady heat transfer. The solution is obtained by the perturbation method. The methods are proposed, how to determine experimentally the interpore heat transfer coefficient. The experimental setup realizing the propozed method is described. It is snown that the affect of porous structure non-uniformity on heat transfer is of the some value as the effect of material porosity. Therefore, heat transfer intensity can be controlled by means of a variation of a porous matirial structure non-uniformity degree. There is suggested a semi-empirical model for a calculation of heat transfer coefficients and hydraulic resistance.
