Default modifying turbulent flow equations
Posts: n/a

is it possible to modify the modeling equations in fluent. I'm trying to do research on improving certain models, for example i'm trying to add terms to the k-epsilon model to see if i can improve it. i'm interested in running the modified model in fluent. is that possible?

Thank you.

Mr. Fadi, It is possible to modify the equations. I am not sure which model especially you want to modify but yes you can add source terms provided Fluent allows an UDF hook to it. I am not sure if you are working with mutliphase flows but my experience with modifications lie in mutliphase turbulence especially with dispersed k-e approach in Eulerian _ Eulerian frame work. We can discuss our views and Ideas if you are interested and working along the same lines. Good Luck! KP

Hello, I was checking the UDFs and the DEFINE macros. it seems i can only change the viscosity equation. what i want is to replace the two k-e equations that form the k-e model with two new equations that I made and run the solver. what i want to do is compare the k-e model vs. the model i want to write.
