This work is devoted to the two methods of modeling porous material. Flow characteristics and, accordingly, the viscous and inertial coefficients for the models of porous materials consisting of spherical particles were obtained by calculation. On the basis of these data conformity assessment of flow characteristics for models of porous materials consisting of spherical particles of arbitrary filling and exactly the same on the geometrical dimensions of the flow model in accordance with Darcy's law was carried out. The data thus obtained were then used to estimate the energy dissipation due to viscous friction in the flow of fluid through the porous body. As a result reached the following conclusions. Firstly, in the absence of information about the viscous and inertial factors that determine the performance curve, data rates with sufficient accuracy can be obtained by calculation in the medium Ansys CFX for periodic fragment of the porous body. Secondly, there is a satisfactory agreement between flow performance for porosity 0,1601 obtained in the medium Ansys CFX for periodic fragments of porous bodies and flow model in accordance with Darcy's law.

The report provides information of using a differential equation of the temperature field of the porous plate, derived taking into account the heating of the skeleton due to the forces of friction when pushing the coolant through the porous plate. Temperature field of the porous plate is determined for different values of porosity and different types of coolant under the boundary conditions of the third kind. Calculation of the temperature field of the porous plate, taking into account the dissipation implemented through programs compiled in Matlab. When the porosity of the insert 0,20 viscous dissipation effect is present, but negligible. Increasing porosity does not lead to significantly different calculation of the temperature condition of the porous insert with and without consideration of viscous dissipation. So keeping the viscous dissipation per thermal state of the porous insert with a porosity of more than 0.2 is not washed away. It was found that the porosity of the matrix is observed increase its temperature. Results showed that when the water flow to the final boundary of the matrix, we can observe both an increase and a decrease in temperature, which indicates the importance of taking account of viscous dissipation and proper selection of both costs and porosities, and the kind of coolant.
