Turbulent Prandtl number is the ratio of ____________(a) turbulent transport of heat to turbulent transport of momentum(b) turbulent transport of momentum to turbulent transport of heat(c) turbulent viscosity to turbulent transport of heat(d) turbulent transport of heat to turbulent viscosityThis question was posed to me by my school principal while I was bunking the class.This is a very interesting question from Turbulent Schmidt Number in portion Turbulence Modelling of Computational Fluid Dynamics

Answer»

Correct ANSWER is (b) turbulent transport of MOMENTUM to turbulent transport of HEAT

The explanation is: Prandtl NUMBER is the ratio of transport of momentum to transport of heat. Turbulent Prandtl number is

Turbulent Prandtl number=\(\frac{Turbulent\, viscosity}{Turbulent\, DIFFUSIVITY}\).
