Normally when I do turbulence problems my practice was to give the Turbulence Intensity & Hydraulic diameter.
But now as I was doing a problem where flow enters in to a cylinder tangentially at four different points on circumference I was not sure if fluent was correctly predicting the flow pattern so I changed the above to Intensity and Viscosity Ratio & kept the deafult values of 10%. This seems to capture the flow better as expected. Can anybody please suggest what kind of inlet BC I should use for turbulent case like this?? Thanks. |
