This paper attempts to determine how the cooling effect of copper alloy B14 varies with roughness, type of water and type of nozzle. Several experiments were performed on 5mmthick copper alloy B14 plates with different combinations of the said parameters. The plates with smooth and rough surfaces were heated up to the 520 ℃. Either tap or distilled water was used as coolant with constant volumetric flow rate, 1.2 L/min. Two types of nozzle were tested, namely, spray nozzle (460.404) and full jet nozzle (544.400). The results of the cooling rate were analyzed on the 1D model. It is observed that distilled water led to a slightly faster cooling rate than tap water, due to oxidation on the copper alloy; rough surface caused fast heat transfer compared to the smooth surface; the domination of nucleate boiling regime was observed in the case of full jet nozzle, as compared to the case of to the spray nozzle, because the full jet nozzle can prevent vapor formation on the material; the spray nozzle covered a larger wetting front area than the full jet nozzle. The results were verified through experiments on the two types of nozzles.

Recently, the thermal management of power electronic converters has gained significant attention due to the continuous trend of developing very compact power electronic converters with high power density. With the evolution of power semiconductor devices, high operating temperatures and large thermal cycles have become possible, necessitating a significant improvement in thermal system designs. Researchers have made significant efforts to develop effective thermal management systems for improving the reliability and lifetime of power electronic converters. This article intends to present a thorough review of thermal management systems employed in power electronics cooling. The applied thermal management techniques have been reviewed from the perspective of electrical parameter regulation and heat dissipation control. Regulation of electrical parameters involves active thermal control, which is a method for controlling junction temperature and thermal cycling of power semiconductor devices. The active thermal control implementation processes reviewed in this article consist of increasing overload capacity, manipulating switching and conduction losses, employing modified modulation process, balancing thermal stress at the converter level, and controlling thermal stress at the system level. Control of heat dissipation can be achieved through direct and indirect cooling of power electronic converters with air or liquid as the coolant. The effectiveness and implementation methods of these cooling techniques, such as channel cooling, phase change material-based cooling, immersion cooling, jet impingement and spray cooling, are reviewed in this paper. Moreover, performance-enhancing ideas and challenges for these techniques are discussed. The primary objective of this review paper is to bridge the existing gap in the literature by offering a comprehensive comparison of commonly employed thermal management techniques.

The present review offers a concise overview of polysulfides, focusing on various techniques for synthesizing polymers with high sulfur content through direct elemental sulfur polymerization. These methodologies encompass condensation, ionic, and free radical polymerizations. Of particular interest is the extensively discussed free radical polymerization type known as inverse vulcanization. The report delves into the diverse applications of polysulfides, spanning areas such as lithium−sulfur batteries, self-healing materials, IR imaging technology, energy storage, controlled fertilizer, antimicrobial agents, oil spill remediation, water-soluble polymers, and separation science, specifically in metal removal from wastewater. Polysulfides showcase distinctive properties, including optical, thermoresponsive, mechanical, and electrochemical attributes. However, it is crucial to acknowledge that this field is not without its challenges. The review briefly explores the current challenges and potential future developments associated with polysulfides. Additionally, it provides a cursory examination of the role of simulations, modeling, and artificial intelligence in advancing the understanding and applications of polysulfides.
