Non-stationary convective heat transfer in an air synthetic impinging jet. Experiment and numerical simulation
Original language description
An unsteady local heat transfer in an air synthetic jet impinging onto a flat plate is experimentally and numerically studied. Measurements of the averaged and pulsating heat transfer at the stagnation point are conducted using a heat flux sensor. The axisymmetric URANS method and the Reynolds stress model are used for numerical simulations. Zones with the maximum instantaneous value of heat flux and heat transfer coefficient are identified. The heat transfer increases at relatively low nozzle-to-plate distances (H/d ≤ 4). The heat transfer decreases at high distances. An increase in the Reynolds number causes reduction of heat transfer.
