摘要
建立一小型圆管外石蜡相变蓄热实验系统,对石蜡的蓄热熔化和释热凝固规律进行实验研究。研究石蜡在圆管外不同位置的蓄热熔化规律,自然对流对石蜡蓄热熔化的影响,得出蓄热熔化时间和熔化厚度的优化值。研究石蜡在圆管外不同位置的释热凝固规律,自然对流对石蜡释热过程的影响。
An experiment set of phase change outside tube was established. Experimental study on paraffin heat storage ＆ melting process and heat release ＆ solidification was carried out. The paraffin heat storage ＆ melting＇s law outside tube in different locations was analyzed. The impact of natural convection to melting process was analyzed, and the optimal melting time and thickness of paraffin phase change have been gained. The paraffin heat release ＆ soiidification＇s law outside tube in different locations was analyzed. And the impact of natural convection to solidification was analyzed.
