Question

Which of these is unmodified for the Shear Stress Transport model and the k-ω model?

(a) Reynolds stress calculation and the k-equation

(b) Reynolds stress calculation and the ε-equation

(c) The k-equation and the ε-equation

(d) Reynolds stress calculation, the k-equation and the ε-equation

I had been asked this question during a job interview.

This is a very interesting question from Turbulence Modelling in division Turbulence Modelling of Computational Fluid Dynamics

Answer 1

The correct choice is (a) Reynolds stress calculation and the k-equation

Easiest explanation: For a Shear Stress Transport model, the k-equation and the calculation of the Reynolds stresses are the same as used in the standard k-ω model. The equation for the transport of ε is transformed into the ω-equation by using the relationship ε=kω.
