Abstract

In this numerical study, the time-averaged and instantaneous heat transfer are assessed in terms of the self-oscillating fluidic device. This fluidic oscillator consists of one inlet, two outlets and two feedback loop channels. The fluid flows a feedback loop channel alternately and results in the impinging jet fluctuation. This self-fluctuating phenomena have successfully been simulated by numerical simulation. As a result, the linear relation between the input flow rate and oscillating frequency is indicated. Utilizing the self-oscillating fluidic device for wall cooling, lots of local maxima of the time-averaged and instantaneous Nusselt number were obtained at the hot target wall. This is because the quasi-steady impinging jet generated by the self-oscillating fluidic device produces the quasi-steady vortex.
