Influence of Induction Box Ports on Near Flow Field Mixing

This paper presents the influence of air blown through an injection nozzle in a circular section induction box on the axial jet and air induction. The effect of the turbulent jet on the axial mean streamwise velocity decay, turbulence characteristics, mass entrainment and temperature distribution in the near flow field of an enclosed numerical space is investigated. Convergence of the steady state simulations is achieved by using the RNG kappa-epsilon turbulence model.
