How to Calculate Y plus?
Y plus calculator uses Y_plus = First layer height*Density of air*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), Density of air (D), Friction Velocity for airfoil (U_{*}) & Kinematic viscosity (ν) and hit the calculate button. Here is how the Y plus calculation can be explained with given input values -> 27.58621 = 0.01*2*1/0.000725.
