Abstract
The study of a two-dimensional, steady, incompressible, turbulent flow of a dual jet consisting of a wall jet and an offset jet has been simulated numerically. The standard high Reynolds number two-equation k-ɛ model is used as the turbulence model. The Reynolds number is considered as 20000 for all the computations because the flow becomes fully turbulent. The merge point and the combined point have been obtained and compared with other results. The central streamline has been plotted and observed to follow an arc of a circle. The momentum flux has been computed along the axial length for the wall jet, offset jet and the dual jet and compared. A similarity profile has been obtained in the downstream direction. A detailed discussion has been provided on the pressure field, Reynolds stress, kinetic energy and its dissipation rate. The jet growth rate in terms of half-width, the decay of maximum velocity and the jet width are presented
