摘要

采用了双流体模型对JPL(Jet Propulsion Laboratory)喷管中气固两相流动以及超声速射流两相流动进行了数值模拟

并研究了可压缩两相流动中气相与颗粒的相互作用规律.自主开发的一般曲线坐标系下二维轴对称可压缩双流体程序Solve2D

对气相求解Navier-Stokes(N-S)方程组

采用k-ε湍流模型

颗粒相求解Euler方程组.对JPL喷管内的两相流场和湍流两相射流流场进行了数值模拟

研究了不同颗粒质量百分数以及不同颗粒直径时的气固两相流场的流动规律.

Abstract

A two-fluid model was applied to simulate compressible two-phase flow in JPL(Jet Propulsion Laboratory) nozzle and supersonic jet two-phase flow.And

the interactional mechanism of gas phase and particle phase

rules of particles flowing at different sizes were studied.Program "Solve2D" solving two-dimensional axisymmetric compressible two-fluid model with body-fitted coordinate system was developed.The program was used to solve gas phase Navier-Stokes(N-S) equations with k-ε turbulence model.For particle phase

Euler equations were solved.Two phases were coupled through source terms.Gas-particle two-phase flow field of JPL nozzle and jet were studied under different particle mass percentages and different particle sizes.
