Y+ Estimation Tool

pete · June 10, 2011, 20:29

A new tool to estimate the wall-distance needed to obtain a desired Y+ value is now available on CFD Online. You can find it under the "Tools" menu, or directly here:

This tool uses the Schlichting skin-friction formula as desribed here to estimate the local skin-friction for a turbulent boundary layer on a smooth flat plate. The density and viscosity given by default in the form is for air at sea-level and room temperature (20°C), but the tool can be used for any kind of fluid if the correct density and dynamic viscosity is given.

Is Turbulencemodel depends on Y+?
