Question

The Navier-Stokes equations are ____ system of equations.

(a) coupled

(b) uncoupled

(c) exponential

(d) radical

This question was addressed to me by my school principal while I was bunking the class.

My question comes from Navier Stokes Equation topic in section Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Right answer is (a) coupled

For explanation I would say: Navier-Stokes equations are called a coupled system of equations because all of the equations should be solved to get the dependent variables.  Equations cannot be solved separately to get the unknowns.
