Numerical experiments have been conducted to verify a computer aided temperature measuring system for real time prediction of fluid temperature from outer surface of the cooling pipe of Liquid Metal Cooled Reactor. The working fluid is sodium. Unsteady two-dimensional calculations are first carried out to investigate conjugated convection-conduction heat transfer in a parallel-plate flow duct of stainless steel wall. Calculated temperatures of the outer surface are then used as input data for predicting the temperature of heat transfer surface by one-dimensional inverse heat conduction method. Bulk temperature of fluid is finally obtained from the temperature of heat transfer surface by means of a correlation equation of steady heat transfer coefficient. Predicted results are in good agreement with true values of fluid temperature.
