Question

What are the dependent variables in the Navier-Stokes equations?

(a) τ,T,p,ρ

(b) p,ρ,T

(c) u,v,w,T,p,ρ

(d) u,v,w,T,p

I had been asked this question in an internship interview.

Question is taken from Navier Stokes Equation in division Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Correct choice is (c) u,v,w,T,p,ρ

For explanation: There are six dependent variables in the Navier-Stokes equations. They are pressure (p), temperature (T), density (ρ) and three components of the velocity vector (u,v,w).
