Question

Which of these is correct about the SIMPLER algorithm?

(a) Velocity is obtained without any correction

(b) Velocity is obtained using the pressure values and the continuity equation

(c) Prediction-correction is used for the velocity field

(d) Velocity is obtained using the pressure values and the momentum equation

The question was posed to me in a job interview.

The query is from Incompressible Flows in section Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer 1

Correct choice is (c) Prediction-correction is used for the velocity field

To explain: Though the pressure field in the SIMPLER algorithm does not need any guess and correction, the velocity field still needs a prediction-correction method. It is found in a similar way as in the SIMPLE algorithm.
