Influence of Reynolds number synthetic jet dynamic in crossflow configuration on heat transfer enhancement

Dual Synthetic Jet Actuator and Its Applications—Part IV: Analysis of Heat Dissipation and Entropy Generation of Liquid Cooling with Dual Synthetic Jet Actuator

“…Compared with the condition without SJs, the effect of an SJ makes the heat transfer increase by about 4.3 times [23]. The SJ promotes fluid mixing in the channel and enhances heat transfer [29]. It is worth noting that the SJ contributes little to the pressure drop in the channel.…”

Cooling performance improvement of impingement hybrid synthetic jets in a confined space with the aid of a fluid diode

“…Ingenious cooling schemes are absolutely essential to achieving effective thermal management of electronic devices to keep their temperatures within a suitable range. A promising cooling technology, called an impingement synthetic air jet, has gradually attracted widespread attention [4][5][6][7], due to its obvious advantages as follows compared with conventional cooling methods, such as natural convection, fan, steady jet: (1) a synthetic jet exhibits higher heat transfer capacity, which can be 4.5-10 times [8], 1.2-1.4 times [9] and 1.4 times [10] higher than those of natural convection, fan and steady jet, respectively; (2) it has no rotating parts, which are conducive to noise reduction, low energy consumption, stability, safety and reliability; (3) it does not need fluid pipe and complex pumping, offering a compact structure and ease of integration. Based on the above advantages, an impingement synthetic air jet is considered to be a more efficient manner for cooling of electronic devices, especially in limited space.…”
