本文对雾化沉积过程流体流动动力学以及合金凝固过程的热量传输进行了详细的理论分析.着重讨论了气体的出口速度、气体和金属熔体的质量流率,金属微滴尺寸分布及运动速度等参量,建立了合金在雾化和沉积阶段的热量传输控制方程。

The dynamics for the fluid flow and the heat transfer in a spray deposition/ rapid solidification process was thoretically analysed. The stress was placed onto modelling such parameters as powder size distribution, gas exit velocity, gas mass flow rate and metal mass flow rate, and series equations governing the heat transfer in the atomization and deposition processes.
