Step 7: Verification & Validation

In order to verify the LES solution to the turbulent pipe flow problem, we will compare it against the solution obtained using standard k-e model.

Turbulent Pipe with k-e model

In the Workbench Project Page, left-click on the downward pointing arrow on the top-left corner of the TurbulentPipeLES project and select Duplicate from the drop down menu as shown in the figure below.

A new project will be created. Rename this new project as TurbulentPipeRANS as shown in figure below.

Next, double click on the Solution cell of the TurbulentPipeRANS project. This will launch the FLUENT solver. Here we will change the viscosity model to k-e model. In the FLUENT window, click on General tab on the left hand side pane. Choose Steady for Time. Click OK for the pop-up warning.
