K-ε-T model of dense liquid-solid two-phase turbulent flow and its application to the pipe flow

Abstract

To predict the characteristics of dense liquid-solid two-phase flow, K-e-Tmodel is established, in which the turbulent flow of fluid phase is described with fluid turbulent kinetic energy Kf and its dissipation rate ef , and the particles random motion is described with particle turbulent energy K v and its dissipation rate e p and pseudothermal temperature

Numerical Simulation of Gas-Particle Turbulent Flow Using k_g-ε_g -k_p-εp-k_pg-θ Turbulence Model

“…The proposed model and k g -ε g -k p -ε p -θ model [5] are then used to simulate gas-particle flows in a swirling sudden-expansion chamber with a swirl number of 0.47 [9] .…”

“…Two-phase turbulence flow attracts more and more interest [1,2] . In developing two-fluid models of turbulent gas-particle flows, there are lots of studies [3][4][5] , such as k g -ε g -k p model, k g -ε g -k p -θ model, k g -ε g -k p -ε p -θ model. But it was found that two-phase turbulence is anisotropic and the anisotropy of particle turbulence is much stronger than that of the fluid.…”
