摘要

The system identification method is one of the most important topics in engineering. An interesting application of this method is to investigate the heat transfer from the exhaust valve, especially the valve burning at high temperatures. This study consists of experimental and analytical work. During experimentation, two co-axial rods were used to transfer heat at their contact surfaces. Using the measured temperatures at different locations on the rods and the analytical method, the temperature distribution of the rods and the heat transfer coefficient of the contact surface were calculated. Using the above calculated temperatures at both sides of the contact surface and applying the system identification method, the temperature transfer function was estimated. Using the transfer function, a computational model was created. The results were compared to previous research work. An experimental apparatus, including an analog to digital board, was designed and set up for the experiment.
