Abstract

The present work describes the algebra involved in the two different temporal discretisation and four different spatial discretisation schemes implemented in the RANS code RANS3D developed in the CTFD Division for computation of unsteady turbulent incompressible flow in complex configurations. All the schemes are tested on two simple test problems to show the effect of the discretisation schemes on the numerical accuracy of the flow solution.
