摘要
针对超声波金属熔体处理机因高温金属熔体的传热而产生的温度快速升高问题,采用ANSYS/FLOTRAN CFD对处理机进行了流场和温度场耦合分析,得到了不同冷却气流量下的换能器温度分布。同时,采用流-固/热耦合共轭传热问题求解方法得到了冷却腔内流固界面的对流换热系数,避免了试验测试的困难,为超声波金属熔体处理机的散热和冷却提供了设计依据。
In order to solve the problem of rapid temperature rise of ultrasonic molten metal treatment device due to heat conduction from high-temperature molten melt, coupled fluid and temperature problem is analyzed by using the ANSYS/FLOTRAN computational fluid mechanics code. The convection film coefficient at the solid/fluid interface in the cooling chamber of the system is obtained by adopting conjugate heat transfer analysis algorithm, to avoid the difficulties in measuring the film coefficient via experiment....
