How to Calculate Y Plus?
Y Plus calculator uses Y Plus = (First Layer Height*Friction Velocity For Airfoil)/Kinematic Viscosity to calculate the Y Plus, The Y plus defined as a non-dimensional distance. It is often used to describe how coarse or fine a mesh is for a particular flow pattern. Y Plus is denoted by Y^{+} symbol.
How to calculate Y Plus using this online calculator? To use this online calculator for Y Plus, enter First Layer Height (y), Friction Velocity For Airfoil (U_{f}) & Kinematic Viscosity (ν) and hit the calculate button. Here is how the Y Plus calculation can be explained with given input values -> 56 = (0.01*3.4)/0.00060714285.
