Hello,

I study on natural convection analysis. In my study, the flow is laminar according to reynolds number. On the other hand, it is turbulent based on Grashof number. When i do not create boundary layer, because flow is very slow and y plus values are max 0.98 on wall surfaces without boundary layers. Are layers required for this case? Also, ı study mesh independency and medium mesh are more similar to experimental results than fine mesh. How can ı comment that?

Finally ı use standard wall functions. Should ı enhancement wall treatment? Does it affect the results?

Please help me!! Thank you.
