Y+ Wall Distance Estimation

Freestream velocity: [m/s]
Density: [kg/m3]
Dynamic viscosity: [kg/ms]
Boundary layer length: [m]
Desired Y+ value: []

Reynolds number: []
Estimated wall distance: [m]

The formulas used are give in CFD-Wiki here. The Schlichting skin-friction formula, as desribed here (equation 21.16 footnote in Schlichting), is used to estimate the local skin-friction for a turbulent boundary layer on a smooth flat plate. The correlation is valid for Re < 10^9. The density and viscosity given by default in the form is for air at sea-level and room temperature (20°C).
