An inverse solution has been derived explicitly for inverse problem of two-dimensional heat conduction in cylindrical coordinate by using Laplace transform technique. The applicability of the inverse solution is checked by using the numerical temperatures with a normal random error calculated from the corresponding direct solution. For a mild measured temperature, the surface heat flux and temperature can be predicted well, while for a rapidly change in the temperature this method is slightly revised by introducing time partition method, in which the whole range of the time is split into some partitions. The solution with the time partitions is found to make the prediction of the surface heat flux and temperature improve. It is reveal that the solution can be applied to experimental data, leading to good prediction.
