The mathematical model of thermal processes and the technique of heat exchange research in the porous cylinder

The analytical model of thermal processes in the porous cylinder which is heated up by an external power source is constructed. Adequacy of the constructed model is checked up by calculations of a thermal condition of porous cylinders of different length at several coolant flow. It is shown, that for the fixed coolant flow there is a limiting length of the porous body which excess does not lead to growth of the heat power. The technique of an estimation of factors of the criteria equations for heat exchange in the porous skew field, based on the constructed analytical model of thermal processes in a porous body is offered. On a concrete example the satisfactory stability of the model to errors of input data and convergence of heat exchange results received by means of the technique to their true values is shown.
