Abstract

The aim of the present work is to develop the computer program to simulate the steady
two-dimensional laminar and turbulent flows. The finite volume method is used to solve the
flow governing equations numerically. The Navier-Stokes equations are solved for the
velocity flow field. Since all the variables are stored at the center of each control volume.
The correct velocity field is then used to solve k-epsilon equations. The eddy viscosity, that
represents the influence of turbulence on the mean flow field, can be calculated from those
values of k and epsilon obtained. The boundary layer on a flat plate is employed as a test
case because it is one of the standard famous problems for the validation of CFD program
and a Reynolds number is chosen at 1400 as a case study. It is found that the computed
results are in good agreement with the available published data. Moreover, the governing
equations are solved by using body-fitted coordinates system so that this computer program
can be developed further for the simulation of laminar and turbulent flows over any object
of complex geometry in the future.
