Flow and heat transfer due to a slot jet impinging on a moving surface has been investigated using a dynamic subgrid scale model of Large-eddy simulation. The velocity of the impingement surface has been varied up to two times the velocity of jet at the nozzle exit. A fractional time-step method has been use to solve the filtered Navier-Stokes equation. Turbulence quantities such as kinetic energy of turbulence, production rate of turbulence and Reynolds stresses, are calculated from the flow field data. Nusselt number distribution over the impingement plate at different surface velocity is presented.
