This paper describes the use of modern computational methods for the verification of mathematical equations, to determine the total heat flow transmitted across a certain surface. ANSYS WORKBENCH is choosen as the computational software for this purpose. Calculations are presented for four models. There is a surface, which the total heat flow is transmitted through is considered as: a simple flat plate, comprising with other flat plate, and thin-walled and thick-walled tube. For each case, the total heat flow is calculated using numerical methods and modem computer methods (ANSYS WORBENCH). Performed results of numerical methods are compared with the results of ANSYS software. The numerical methods are considered as a referent. The error of ANSYS calculations in comparison with the the numerical is calculated. The heat transfer by conduction is described for all presented models. Finally, the results of temperature distribution and heat flux distribution for each simulated case are presented.
