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 equationThe 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»

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.
