【摘要】 本文以脉冲激光为热源,以高响应、高精度铂薄膜电阻为测温和加热元件,进行了低温工质(液氮)超急速爆发沸腾的实验研究。利用显微放大摄影系统对不同工况的沸腾过程进行了拍照,发现不同系统变量:如试件表面状况、激光参数对低温工质(液氮)超急速爆发沸腾行为有着重要的影响。更多还原

【Abstract】 The experiment of rapid transient explosive boiling was studied under low temperature environment, a high-power pluse laser as the source of heat, platinum thin film with high response and precision as both the measuring temperature and heated element. Boiling process under different condition were taken pictures depending on the use of microscopy in order to find how system variables such as surface condition, laser parameters effect the rapid transient explosive boiling under low temperature environment.更多还原
