Question

The source term in the pressure equation of the SIMPLER algorithm is obtained using ___________

(a) velocities in the previous iteration

(b) pressure in the previous iteration

(c) pseudo-neighbours

(d) pseudo-velocities

The question was asked in an interview.

I need to ask this question from Incompressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer 1

The correct answer is (d) pseudo-velocities

To explain I would say: The discretized pressure equation of the SIMPLER algorithm is the same as the pressure correction equation obtained for the SIMPLE algorithm. The only difference is that the source term here is obtained from the pseudo velocities.
