1.	__________ relates turbulent viscosity and diffusivity.(a) Reynolds number(b) Reynolds analogy(c) Reynolds-Averaged Navier-Stokes equations(d) Favre-Averaged Navier-Stokes equationsI had been asked this question in my homework.My query is from Turbulent Viscosity topic in chapter Turbulence Modelling of Computational Fluid Dynamics
Answer» Right choice is (b) Reynolds ANALOGY For explanation I would say: Reynolds analogy relates the turbulent momentum and heat transfer. It states that “both of these (turbulent momentum and heat transfer) are due to the same mechanism called turbulent eddies and hence the VALUES of turbulent VISCOSITY and diffusivity will be close to each other”.
