Effect of plate spacing of impingement air jet on flow and heat transfer characteristics

In this paper the flow and heat transfer characteristics in the turbulent confinement impinging air jet have been numerically analyzed. Two-equation turbulence model, $\kappa-\varepsilon$, have been used. Mass, momentum, energy, turbulent; kinetic energy and turbulent kinetic energy dissipation rate equations were solved by the PHOENICS package program. Velocity, turbulent kinetic energy, turbulent kinetic energy dissipation rate and heat transfer characteristics in the impinging region have been predicted by finite volume scheme for the various, plate spacings.In this paper the flow and heat transfer characteristics in the turbulent confinement impinging air jet have been numerically analyzed.
