Comparative study of simulation of incompressible two-dimensional laminar Duct flow in ANSYS FLUENT™ and MATLAB™

Makrand Khanwale


A finite difference method is described for computation of dynamics of pipe flow in two
dimensions. The In-house code solves the pressure –velocity coupled momentum and the
continuity equations using Semi Implicit Pressure Linked (SIMPLE) algorithm and postprocesses
the data. The In-house code has been written in MATLAB™. A run for the same
geometry in ANSYS FLUENT™ is also put on for two-dimensional laminar flow and a
systematic comparative study is presented between the two codes. The results are tabulated
with their percentage accuracy with respect to the analytical solution.
