Hi Jade M,

thanks for your effort. I do use FLUENT. In the mean time they implemented the 4 eqn SST. I am not sure how precise this is. I will start some benchmark calculations. I found some...

But how to define the zone. Do I have to use boundary layer theory and calculate the thickness of the boundary layer over length?

Hi,

the development of the boundary layer does depend on the turbulence level. The critical Reynolds number is a function of the T.I.. So, in case of relaminarization. How to model that case?

Hi there,

I do have another problem. I try to understand the effects dominating the problem of a flat plate within a channel. Is it true that I will get a laminar boundary layer starting at the...

@DoHander


Thanks. I will try to define several domains within ICEM. Do you think I will be able to enable different turbulence modells, each best able to predict the effects in the particular...

Hi,

as far as I know you cant decide wether or not a flow field includes turbulence by looking at the streamlines given by CFD. The RANS models do just add terms like additional viscosity. The...

Hi,

that is what I thought. But if I am not able to clearly detect the transition point I won't be able to apply different conditions on my model. My problem is that I am not sure wether or not...

Applying turbulence model on laminar flow

Hi,

what happens when I do apply a turbulence model on a laminar flow field?

Thank you for your answers
