Numerical Simulation on Fluidic Oscillator by Supersonic Flow Mechanism

Fluidic oscillators are designed in a supersonic condition and pulsating jet effects achieved in this investigation. Computational Fluid Dynamics (CFD) of 3D unsteady flow was performed on impinging jet heat transfer performance by using fluidic oscillator. The Reynolds-averaged Navier–Stokes turbulence model reached the thermal flow capacity of the fluid oscillation at unstable flow conditions. The results are presented by the average flow fields and heat transfer capability at supersonic conditions. Navier–Stokes equations are performed that the dynamic flow fluid and heat transfer well agreed for dissimilar Reynolds number. During the fluidic motion, oscillation frequency will saturate in a particular value when increases the applied pressure. The impinging jets of self-oscillation is more advantageous while increasing average Nusselt number for heat removal performance and adopting more cooling impinging area. Feedback Channel (FBC) at inside the pressure different at inlet and outlet flow course of the FBC channel is evaluated by internal fluid dynamics. The loops supplied in the mixing chamber provide unique rotational properties with a change in the course of the fluid in the FBC. As a result of heat transfer, the impinging jet was performed at the peak heat exchangers, multi-level and thin film cooling applications of refrigeration development.KeywordsNavier–StrokesHeat transferDynamic flowFeedback channelComputational fluid dynamicsImpinging jetFluidic oscillator.
