| Abstract: | On the basis of an accurate solution for the thermal transfer problem of one dimensional semi-infinite size,a general solution with a coefficient needing to be determined is given.Using conditions to determine solution for the problem,a transcendental equation including the coefficient needing to be determined is obtained.Applying numerical method to solve the transcendental equation,thus an accurate solution for the thermal transfer problem is received.Calculation results showed that the values of the accurate solution accords well with the values of the approximate solution in a certain scope of the parameter. |
