Influence of waveforms on the heat transfer behavior of multi-orifice synthetic jet

ABSTRACT

This experimental investigation aims to analyze the heat transfer capabilities of both single and multi-orifice SJs (MOSJs) for varied waveforms(sine, square, and triangular), at a fixed Reynolds number (3525). The jet-to-plate distance and pitch radius is varied in the range of 1–19 and 3.8–8 mm, respectively. The MOSJs at pitch radius (PR) of 3.8 mm shows 30.6% higher average Nusselt number than single SJs. For a PR of 8 mm, the Nusselt number contour shows multiple heat transfer regions adjacent to the stagnation point; however, a single heat transfer region is evident at PR of 3.8–6 mm.
