An experimental and numerical study on heat transfer enhancement of a heat sink fin by synthetic jet impingement

Current Review on Numerical Simulation of Synthetic Jet (SJ) Cooling

“…Lehnen et al, [12] came to the conclusion that the H/d and frequency have the most effects on the SJ ability to dissipate heat. It was discovered by Huang et al, [16] that frequency increased the fin surfaces' average HTC almost linearly. At a fixed operating frequency, the HTC increases linearly with increasing diaphragm amplitude.…”

“…In a numerical study, Huang et al, [16] investigated the HTC brought about by impinging a SJ flow onto a longitudinal fin employed in an electronic cooling system. The impacts of several factors, such as H/d and diaphragm movement frequency and amplitude, are noted.…”

“…CFD software ANSYS Fluent with the Semi-Implicit Method for Pressure Linked Equations (SIMPLE) technique has been widely use among the researchers in order to simulate the incompressible flow. [16,25,29,40] In order to take into account turbulent and viscous effects, the k-omega SST model is mostly chosen to solve the mathematical model [10,16,19,25,26,40]. The turbulence model was used because it accurately depicts the flow in the vicinity of the wall and performs better when dealing with the large flow fluctuation [56].…”

Heat Transfer Augmentation through Different Jet Impingement Techniques: A State-of-the-Art Review

“…Synthetic jets are jets having flow with oscillation in such a manner that the time-averaged velocity remains zero. In this regard, Huang et al [106] performed an experimental and numerical investigation to study the heat transfer performance of a heat sink longitudinal fin from an electronic cooling system using the active jet excitation technique of synthetic jet impingement. The study was based on analyzing the effect of the amplitude and frequency of movement of the diaphragm and the jet-target surface spacing.…”
