In this study, the numerical analysis of turbulent flow and heat transfer of oscillating impinging circular jet on concave cylindrical surface has been investigated. In this way, the averaged Navier-Stocks equations for turbulent incompressible flow in an unsteady state with RNG k-ε turbulent model and in 3D computational space were solved. The effects of oscillation frequency, amplitude of oscillation and Reynolds number on Time-averaged Nusselt number Distribution in concave surface were studied. The obtained results show that applying the pulsating jet in the range of 50 to 200 Hz can increasing heat transfer from concave surface in comparison with the steady jet. Furthermore, increasing Re number from 10000 to 40000 and amplitude of oscillation from 0.4 to 1, leads to the increase of timeaveraged Nusselt number. [ABSTRACT FROM AUTHOR]
