Turbulence Part 3 - Selection of wall functions and Y+ to best capture the Turbulent Boundary Layer

Note: this is an old post.  The updated post series from 2020 is LEAP's 3-Part Series on "What y+ should I use in my simulations?" which is available here: Part 1 – Understanding the physics of boundary layers Part 2 – Resolving each region of the boundary layer Part 3 – Understanding impact of Y+...
