The mass transfer equation was introduced into heat transfer model of falling film evaporation. The radial velocity, mass diffusion coefficient and variation of film thickness were taken into account.
将传质方程引入到垂直管降膜蒸发传热模型中,求解时考虑了径向速度、质量扩散系数和膜厚变化对传热的影响。
The simulated radial distribution function and diffusion coefficient also accord with experiment basically. Rather, the pair distribution function is consistent with the literature reported.
模拟获得的径向分布函数和扩散系数的值与实验基本吻合,分子间作用能分布也与文献报道的趋势一致。
In a certain inlet velocities, vaneless diffusers with diffusion type have higher pressure recover coefficient and can reduce the radial size.
采取扩张型非平行壁无叶扩压器,在一定的进口速度下,可望有较高的压力恢复系数,且可以缩短径向尺寸。
