BY THE CALCULATION OF TEMPERATURE FIELDS AT VARIABLE HEAT TRANSFER COEFFICIENT AND TEMPERATURE

Based on the analysis of convective heating (cooling) the bodies of regular geometric shape in quasi-stationary stage derived integral equation, with which you can approximately solve the problem of heat conduction from the non-linearity in the boundary conditions. Developed engineering method for calculating the temperature fields at a variable rate of heat transfer and temperature. Comparison of the method with the exact numerical solution shows that the error in determining the temperature does not exceed 6% and it can be considered quite acceptable for engineering calculations. The formulas for the calculation of axial thermal stresses.
