Abstract
The multi-perforated wall of synthetic jets bas been analyzed to enhance heat transfer under laminar and turbulence cross-flow and for several dynamic configurations. To study the role of cross-flow and synthetic jet interactions, a dedicated experimental set-up was developed with convective heat transfer coefficients along the wall. Multi-perforated results were directly compared to single synthetic jet data. Sensitive parameters such as jet frequency, piston amplitude displacement and cross-flow velocity were determined. Heat transfer from the synthetic jet device can be amplified from 23 to as much as 175% depending on experimental conditions. The role of multi-perforating plate with regard to the single row configuration is clearly demonstrated. It is reinforced by continuous interaction between the main flow and synthetic jets.
