Question

Turbulent Schmidt number is used to solve ____________

(a) mass transfer in a turbulent boundary layer

(b) compressible flows

(c) boundary layer flows

(d) heat transfer in a turbulent boundary layer

I had been asked this question in a national level competition.

Question is from Turbulent Schmidt Number in section Turbulence Modelling of Computational Fluid Dynamics

Answer 1

Correct option is (a) mass transfer in a turbulent boundary layer

For explanation I would say: As the turbulent Schmidt number relates momentum and mass transports, it is used to solve mass transfer in turbulent boundary layers. In general, it is used along with the Reynolds analogy.
