Blended turbulence viscosity

Properties​

  • Continuous wall function that blends contributions from the viscous sub-layer and logarithmic regions
uτ=(uτ,sub4+uτ,log4)0.25 u_\tau = \left(u_{\tau,sub}^4 + u_{\tau,log}^4 \right)^{0.25}

Usage​

The wall function is specified using:

wallPatch
{
    type            nutUBlendedWallFunction;
    value           XXX;
}
