Experimental study on the method and performance for heat transfer of jet impingement

A new kind of experimental equipment has been established to prepare for making a study on the heat transfer of jet impingement when quaternary mixed nitrate will be regarded as working fluid. In order to verify the validation of experimental equipment and method, a experimental study on the heat transfer of jet impingement using the water has been carried out, whose results also have been achieved. The results at the stagnation point showed that good consistences for water are found between the current results and some results from classical correlation, which indicate the accuracy and reliability of experimental equipment and method. Meanwhile, the influence of temperature for heat transfer characteristics of stagnation has been made when the temperature is changed, whose results show that thermophysical properties of working fluid have a enormous influence on the Heat transfer performance. The experimental results in this paper provide a necessary technical guarantee for the study of heat transfer of jet impingement utilizing the high temperature molten salt.
