Turbulent flow field and heat transfer in an array of slot jets impinging on a moving surface have been numerically investigated by Large-eddy Simulation (LES) technique in the range of Reynolds numbers between 500 and 3000. The surface velocity, directed perpendicular to the jet, is varied up to two times the jet velocity at the nozzle exit. The Nusselt number distributions for various surface velocities are presented. It has been observed that on one hand increasing velocity of the impingement plate reduces heat transfer, while on the other hand distribution of Nusselt number over the impingement surface becomes more uniform with the increased surface velocity.
