1.	Turbulent Prandtl number is used in CFD to ____________(a) change viscosity profiles(b) change temperature profiles(c) modulate heat transfer results(d) modulate velocity profilesThe question was asked during an internship interview.My question comes from Turbulent Schmidt Number in section Turbulence Modelling of Computational Fluid Dynamics
Answer» Correct choice is (c) modulate heat transfer results For EXPLANATION: Prandtl number relates MOMENTUM transfer and heat transfer in a turbulent FLOW. So, it is used in turbulent flows with heat transfer. In general CFD problems, it is used to tune the heat transfer results.
