As title, and again, I am asking the number of grid points along one-direction, using finite volume method, low-Reynolds-number turbulence models, for pressure drag and heat transfer.

I am not sure if I've provided enough infomation for my question or not. If more input needed, please light me up.

This is more difficult to answer. Seems there is not a Yplus-like parameter here. Why don't you try a grid independence study after you get a solution?

Also depends on the overall accuracy of the code used.
