Non-stationary flow and heat transfer in a synthetic confined jet impingement
Original language description
Heat transfer in a synthetic impinging jet is studied experimentally and numerically. A heat flux sensor is used to measure averaged and pulsating heat transfer. Mean and fluctuational components of flow velocity and heat transfer are simulated using the axisymmetric non-steady-state Reynolds averaged Navier-Stokes equations and the Reynolds stress model. The instantaneous and pulsating heat flux at the stagnation point and along the radius of the target surface are obtained. The experimental spectra of heat flux fluctuations are given. The studies are carried out with variation in the nozzle-to-target distance, and frequency of the synthetic jets.
