Hello!

 

Does anyone know how to add roughness on a surface or make the surface rougher in Fluent? This surface is shown below and is defined as no-slip wall in Fluent. Large eddy simulation is used to model turbulence.

Thanks!

Whenever you open wall boundary hit F1 then search after roughness. But this would not work for LES you need hybrid approach.

Hello Amine,

 

Thanks for your reply. I am not familiar with hybrid approach. Do you have any references?

 

Best regards!

Check the scale resolving methods in the documentation. Moreover carry out a literature study on that.

Best regards,
