Abstract

Existing methods for determining the characteristics of the nonstationary heat transfer process (temperature field, heat transfer coefficient, heat flux density, surface temperature) are considered and analyzed when cooling silver spherical and cylindrical thermo-probes. New analytical solutions are proposed using a special program IQLab, which increase the accuracy of calculations when testing the cooling capacity of various liquids. The results of the calculations are compared with the experimental data.
