multiphase mixing Problem with MRF model in MixSim

Srinivas

hi all

I am Srinivasa T, a postgraduate student from IITMadras, doing my project. My project is as follows:

A open mixing tank fitted with internal helical coil and a stirror/impeller, with some volume fraction of solid particle of given dia(micro meters). no inlet and outlets to tank.

Problem Description:

My project is to study the effect of internal helical coils on solid suspension in mixing tanks/sparged vessels. I am using "Multiple refence plane"(MRF) model for impeller and "Eulerian Granular model" as multiphase model and "Standard k-epsolon model" for turbulence. Iam using "MixSim 2.o" provided by FLUENT Inc.for simulation.

Problem I am facing:

I am confused what are all the boundary conditions should i give for this problem when i shift to FLUENT after geometry construction and meshing in MixSim. So i need your help in this regard. Kindly suugest me how can i define boundary conditions for this problem.

thanking you,

your sincerely, Srinivasa T M-Tech (Chemical Engineering) IIT Madras Chennai.
