Class
Foam::compressible::LESModels::lowReOneEqEddy
Description
One Equation Eddy Viscosity Model for compressible flow
@verbatim
d/dt(rho*k) + div(rho*U*k) - div(muEff*grad(k))
=
-rho*B*L - ce*rho*k^3/2/delta
and
B = 2/3*k*I - 2*nuSgs*dev(D)
where
nuSgsHiRe = ck*sqrt(k)*delta
nuSgs = (nu/beta)*(1 - exp(-beta*nuSgsHiRe/nu));
