摘要：
Two space marching methods for solving one-dimensional nonlinear inverse heat conduction problems developed earlier are validated using data obtained during emergency cooling simulation of PWR pressure vessels. The model of pressure vessel was preheated at 350 ∘C and then cooled by injection of cold water at 20 ∘C. Based on the vessel temperature histories measured at the distance of 50 mm from the inner surface and at the outside surface the transient temperature distribution in the pressure vessel was obtained. The comparison of the results obtained by both space marching methods with experimental data shows high accuracy of the space marching methods.
