ruzfactor is on a distinguished road
I have been given a paper of Axisymmetric Sudden Expansion and, a mesh of fluent to solve it and to compare the results with that of written in the paper. But I am very much confused, where to start my project! I have managed to converge the solution twice but I don't actually getting any clue of guessing the proper initial conditions. How can I compare the data from fluent with that of the paper?How would I guess the correct turbulence?? Can some one guide me through?? plz I need help...
