Research on Metal Atom Evaporation With 2-D Steady Flows

摘要: 从由Boltzmman方程而来的BGK方程出发, 数值模拟长槽型坩埚二维平面蒸发动力学过程, 着重对分离器中加入精料收集板、贫料收集板和热离子收集板时蒸气原子的空间物理特性进行数值模拟和分析, 并对收集板的吸收率和温度以及Kn变化时, 蒸气原子的空间物理特性进行了分析。

Abstract: Study of the evaporation is one of crucial technology in AVLIS (atomic vapor laser isotopic separation). The research work on physical parameters of atomic vapor in separation region such as the 2 D distributions of velocity, density and temperature provides some important scientific data for designing separator in AVLIS engineering. In the paper, the distribution of density, velocity and temperature is presented and some related interpretations for them are also given on the basis of BGK equation, when many absorbing boards are considered.
