Dear all,<\/p>\n
I Intend to simulate slurry flow that consists of air, water, and ore, so it will be three phase simulation in Ansys CFX. The phase modeling that I did was:<\/p>\n
I used in-homogeneous multiphase model (with standard free surface model) and homogeneous turbulence model. I want to simulate a steady-state simulations of the slurry fills a box with one inlet and several outlets (at first the box is filled with air only).<\/p>\n
I faced a problem when I modeled the ore particle-particle interaction with kinetic theory. The problem that I faced was the simulation was not converging. It showed residuals that do not converge and go up and down very unstable. However, when I turn of the kinetic theory model, the result can be obtained and more stable (even though it did not converged to the residual target, but still stable than when I turn on the kinetic theory model).<\/p>\n
I already read several journal regarding multiphase flow that involves solid, activating kinetic theory model is best for modeling particle-particle interactions.<\/p>\n
Does anyone have suggestions to solve this problem?<\/p>\n
Thank you very much.<\/p>\n","protected":false},"template":"","class_list":["post-304421","topic","type-topic","status-closed","hentry","topic-tag-ansys-cfx","topic-tag-eulerian-multiphase-model-1","topic-tag-multiphase-flow"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
