| 摘 要： | 基于计算流体力学和传热学,建立等离子喷涂枪喷嘴冷却水流动和换热分析模型,以SIMPLE方法对其进行了耦合计算.结果表明,喷嘴冷却存在薄弱部位,即热源附近的喷嘴壁面和喷嘴后端的密封垫圈.在此基础之上,对不同冷却水流速和流向进行了对比分析,得出较为理想的冷却水流速,合理的进水方式.

| Abstract: | Based on CFD and heat transfer theory,a model of the nozzle in a plasma sprayer is developed.The flow and heat transfer of the cooling water are simulated with coupling.It is found that the wall near heat source and the gasket in the back of the nozzle are the most deficient cooling parts.Then different parameters of cooling water are analyzed,and the optimum velocity and direction of cooling water are found. |
