摘要

首先

建立了湿蒸汽凝结流动的双流体模型

考虑了湿蒸汽两相流动中相间的速度滑移、耦合以及湍流扩散作用的影响.然后

针对蒸汽透平叶栅中流动的湍流特性

在单相湍流计算中数值模拟精度相对良好的两方程SST k-ω湍流模型基础上

参照颗粒湍能输运方程理论

推导建立了SST k-ω-k

湿蒸汽两相流动湍流模型

模型中引入了液相黏性、导热及扩散系数等拟流体概念.对二维叶栅中存在自发凝结的湿蒸汽流动进行的数值模拟表明:建立的数值模型表现良好

明显优于单流体模型

特别是吸力面的压力分布模拟精度有很大提高

具有较高的精确性和可靠性.由于实验数据的匮乏

数值模拟中发现的汽液两相的动力特性以及液相的参数分布有待于进一步的实验来验证.

Abstract

A two-fluid model of wet steam flow with condensation was established firstly

in which the velocity slip and coupling between the steam and liquid phases and the turbulent diffusion were considered. Then based on the transport equation theory of particle's turbulent kinetic energy

the SST k-ω-k

two-phase turbulence model was derived from the SST k-ω model

which behaves well in numerical simulation of single-phase turbulent flow. In this model

some concepts of friction fluid for the liquid phase were adopted such as viscosity

thermal conductivity and diffusion coefficient. The simulation result of wet steam flow with spontaneous condensation in a two-dimensional cascade indic

ates that the present model behaves well and is obviously superior to the single-fluid model. In particular

the pressure distribution simulation is more precise on the suction surface. The dynamic characteristics of the two-phase flow and the parameter distribution of liquid phase predicted by the present numerical simulation need to be verified by further experiment.
