Abstract

In this study, the flow field and the impingement heat transfer of fluidic oscillators at narrow spaces are investigated numerically. Simulations are performed in 2-D, incompressible, and unsteady conditions and the aim is to analyze the effects of the jet to wall distance, the external nozzle angle, the Reynolds number, and removing the external nozzle on the heat transfer performance. Also, for a comprehensive review, the results of the fluidic oscillator are compared with the results of the steady jet. To ensure the validity of the numerical simulations, two experimental researches are applied for the fluidic oscillator and the steady jet and a good agreement is observed between the present simulations and the experimental data. The results show that increasing the distance in fluidic oscillators causes a maximum decrease of about 11% at the Nusselt number of the stagnation point, while employing the various distances does not have a significant effect on the steady jet. In addition, the configuration of the different external nozzle angles affects the Nusselt number, but this influence does not have a monotonic behavior. Furthermore, the Nusselt number increases by removing the external nozzle. When the Reynolds number increases for the fluidic oscillator and the steady jet, the Nusselt number of the stagnation point increases by at least about 22 and 28%, respectively.
