The pressure equation in the incompressible flows contain _________(a) Taylor series terms(b) Hermitian operator(c) Laplacian operator(d) Fourier series termsI got this question in unit test.Question is taken from Incompressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer»

Correct answer is (c) LAPLACIAN operator

Explanation: The POISSON’s EQUATION which is formulated for FINDING the pressure values has a Laplace operator. This is the product of the divergence operator in the continuity equation and the gradient operator in the momentum equation.
