Abstract
A numerical study of three-dimensional laminar and turbulent wall jet issuing from a rectangular orifice is presented. The numerical simulation was based on k-e model. The Navier-Stokes, energy, and turbulence quantities are solved using the finite difference primitive variable method with staggered grid technique. The flow field characteristics are studied in laminar flow for Reynolds numbers up to 3000 and in turbulent flow for Reynolds numbers up to 56000. The results show that the spreading rate of the jet is higher at low Reynolds numbers and the decay of axial velocity is less at high Reynolds numbers. The numerical results obtained are compared with published experimental results and found to be in reasonable agreement
