Numerical investigations to determine the heat transfer characteristics of an impinging synthetic jet has been carried out. On the basis of the designed operating frequency and orifice width of the synthetic jet actuator, chosen to meet a jet formation criterion applied in a previous work, numerical simulations have been carried out by means of a turbulent fluid dynamics commercial code. Stagnation heat transfer characteristics and local Nusselt number behaviours are presented for various Reynolds numbers and nozzle-to-plate distances. The results are in good agreement with previous findings of literature and confirm the effectiveness of such devices as opposed to the more traditional continuous jets.

Abstract
Numerical investigations to determine the heat transfer characteristics of an impinging synthetic jet has been carried out. On the basis of the designed operating frequency and orifice width of the synthetic jet actuator, chosen to meet a jet formation criterion applied in a previous work, numerical simulations have been carried out by means of a turbulent fluid dynamics commercial code. Stagnation heat transfer characteristics and local Nusselt number behaviours are presented for various Reynolds numbers and nozzle-to-plate distances. The results are in good agreement with previous findings of literature and confirm the effectiveness of such devices as opposed to the more traditional continuous jets.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
