unable to track particle(single injection)
i got a problem while tracking the particle in flow using DISCREET PHASE MODEL. My problem consists of caturing of sand particles ( single injection ) in a duct (2-D).the particle has to either captured by a water drop which is located in the duct or escape .the flow is axis symmetric along the horizontal axis of duct and the water drop is on the axis.When i inject a particle offset to the axis from entrance of duct FLUENT tracks particle for a range of offset distances (approx till Y= 0.4times of drop diameter)but after that when i increase offset distance FLUENT is unable to track particle at the point of injection only.This happens for different diameter of particles at different offset distances. sum of the data tht i used is as follows (laminar flow ,drop dia = 100 micrometre particle dia=2 micrometer, velocity of flow = 5 m/s i.e. Re=32 , Fluid=air) Inlet boundary condition=velocity inlet oulet B.C= Pressaure outlet Drop=as a wall
DRAG RELATIONSHIP USED IN DPM= spherical law no interaction ENERGY EQUATION NOT TO B SOLVED. If anyone can help me please mail me at avinashkumar79@yahoo.com |
