An implicit finite volume algorithm based on the numerical solution of Reynolds Averaged Navier stokes (RANS) equation is presented for prediction of incompressible turbulent flow in and around complex configuration. The algorithm uses boundary-conforming, structured grid, collocated variable arrangement with cartesian velocity components as dependent variables, pressure-velocity solution strategy coupled to different low-diffusive discretisation schemes for evaluation of the convective flux at cell faces, first and second order schemes for temporal discrtetisation and the eddy-viscosity based k -e model with different near wall treatment for turbulence simulation. Capability and limitation of the algorithm are demonstrated through five different application examples of varied complexities.
