The mixing length model can be used to get the turbulent scalar fluxes

1.	The mixing length model can be used to get the turbulent scalar fluxes also using _____________(a) turbulent Prandtl/Reynolds number(b) turbulent Reynolds/ Schmidt number(c) turbulent Prandtl/Schmidt number(d) turbulent Reynolds/Nusselt numberThis question was addressed to me during an internship interview.My doubt is from Mixing Length Turbulence Model in portion Turbulence Modelling of Computational Fluid Dynamics
Answer» The correct answer is (c) turbulent Prandtl/Schmidt number To explain I would say: Mixing LENGTH model uses the turbulent viscosity coefficients. If a RELATIONSHIP can be established between the turbulent viscosity and turbulent DIFFUSIVITY, the model can be USED for turbulent SCALAR fluxes. This relationship is established by the Turbulent Prandtl/Schmidt number.
