Question

In which of these steps are the pressure-correction equations obtained in the PISO algorithm?

(a) The first predictor step

(b) The first corrector step

(c) The second predictor step

(d) The second corrector step

Answer 1

Correct option is (b) The first corrector step

Explanation: The pressure-correction equation is obtained by applying the corrected velocities to the continuity equation. This pressure-correction equation is then used to get the first pressure correction value.
