1.	Which of these statements is correct about the transient SIMPLE algorithm?(a) No additional terms are needed in the continuity and pressure-correction equations(b) No additional terms are needed in the continuity equation(c) An additional term is needed in the continuity and pressure-correction equations(d) No additional terms are needed in the pressure-correction equationThis question was addressed to me in a job interview.This intriguing question originated from Transient SIMPLE and PISO Algorithms in section Transient Flows of Computational Fluid Dynamics
Answer» RIGHT choice is (c) An ADDITIONAL term is needed in the CONTINUITY and pressure-correction equations The explanation is: The transient (unsteady) terms are added to the continuity equation. As the transient SIMPLE algorithm DERIVES its pressure-correction equation from the continuity equation, the pressure-correction equation also gets some additional terms.
