Thermophysics and Thermal Power Engineering| Summary: | With the help of substitution obtained fairly simple analytical solution for the quasi-stationary temperature field in the bodies of the canonical form when the heat transfer coefficient and the temperature of the environment is a function of time. From this it follows as a special case of the solution in the case of constant temperature environment. Comparisons with the exact solutions have shown that the error in determining temperature fields does not exceed 6 %, and it can be considered quite acceptable for engineering calculations. Formulas for calculating of the axial thermal stresses has been suggested. |
