摘要 基于沸腾气泡动力学,完善关于二次核化的喷雾冷却模型,得到的模拟结果表明二次核化是喷雾冷却具有强散热能力的主要原因,雾化颗粒数目已经成为影响沸腾喷雾冷却的最关键因素。研究关于计算气泡的特征时间需要得到二次核化沸腾气泡个数的一些具体方法,对喷雾冷却模拟和机理研究具有指导意义。 Based on the boiling bubble dynamics,anti to Degm to wew improve on nucleation Spray cooling model. The results indicate that secondary nucleation is main factor of heat transfer enhancement. This thesis will study on some constructive approaches for calculate thecharacteristics of bubble time obtain secondary nucleation boiling bubble number.
