I need a guideline for FLUENT!! plz..

ruzfactor · November 12, 2010, 16:40

I have been given a mesh of an Axisymetric Sudden Expansion. I have to develop a velocity profile at several locations downstream of the expansion, static pressure and bed shear profile, and compare with the results of an experiment (I have been provided with a paper, but its too complicated!). I need help on how to approach this type of problem? I'm new to CFD and geting frustrated on how to solve this problem. I have managed to converge the solution twice using some guesses based on the experiment but I don't know what is right and what is wrong. Basically the experiment is a multiphase problem but I have to solve the problem as a single phase.
can someone help me on how to start from the scratch??? I really need help.. plz...

I'm posting here the mesh file and the paper so that someone can explain me how to approach this problem. I'm really struggling to understand what to do next? I need help badly
