Dear all,

I am wondering how do I define my number of cells in the boundary layer given that I know my y+ which is the distance of first cell away from the wall.
Let say I got y+ of 0.5 to 20 and for my region of interests(rotating surface) my y+ is 5 (therefore I use enhanced wall treatment). However, according to theory, I need to have 10 cells within the viscous sublayer. Y+ 0 to 5? or approx 0 to 10?

Can someone advice me on how to know whether my cells are within the BL.

I know that for first cell let say 0.1 mm next one is 0.12 (Growth ratio of 1.2) and 0.144 mm etc. But I am curious how I know whether it is still within the buffer layer before it escape to outer layer.

Thanks

Regards,
J
