Abstract Synthetic Jet (SJ) has emerged as a promising heat transfer enhancement fluidic device, giving tough competition to other existing thermal management techniques. This paper aims to present a brief review of thermal enhancement using SJ along with the various parameters that influence its flow-field and cooling performance. Although the SJ flow dynamics in the quiescent environment is widely reported, the near-field flow and heat transfer characteristics of a synthetic jet of the slot with high aspect-ratio are not extensively explored, specifically at low excitation frequencies. In addition, this paper provides deep insights into the effect of parameters such as optimum jet-heated surface separation distance, dimensionless stroke-length, excitation frequency, number of jets and geometrical parameters on the heat transfer performance of the SJ. Finally, a list of potential gaps and challenges are presented for laying down the foundation for future research.
