Influence of argon, propane and ethane viscous dissipation on the thermal state of a porous plate

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.
