Hi,

What number element do you use?

I think that if number element is about between 1 and 2 million, you can use K W SST that is better high Re turbulence models.

Hi Anand and Ali,

I also would recommend k-omega because it is the only system which has a clean phyiscs basis, see attachment (published in Physica Scripta 3 years ago). With the SST add-on I personally have no experiences, but a counter questions: what is your Reynolds number based on mean-flow data and diameter of the "pipe"?

HI ALi Sam,

I have around 1.5 million elements.

Hi Helmut Zuagfeld Baumert Sir,

I have transition stage where Re number varies. It is the case of flow over transonic rotor blade. I will go through the paper attached by you and will let you know if i have any further doubts.

Thank you,

Regards,

Anand
