摘要

ABSTRACT The present experimental and numerical analysis reports the thermal performance of circular synthetic jets involving sinusoidal and triangular waveforms. The Reynolds number, dimensionless axial distance, the dimensionless stroke length, and the driving frequency are varied within 4150–5600, 1–18, 5–13, and 80–250?Hz. The average Nusselt number obtained from the triangular waveform exhibits 11 higher heat transfer than the sinusoidal waveform of the synthetic jet. The thermal characteristics of synthetic jet and steady jet are compared, and it is found that synthetic jets exhibit 38.6 higher thermal performance than continuous jets in the far-field region. Also, correlation is proposed for the average Nusselt number.
