Default conical diffuser and turbulence model
Posts: n/a
Hi all,

I want to model a conical diffuser in 2D, with entrance velocities in the range of 100-250 m/s. As these velocities imply strong turbulence inside the diffuser, I want to get this turbulence (or better the turbulence intensity) right. Can somebody tell me which turbulence model is best suited for this application?

Thanks in advance and best regards, Markus
