“…Another reason for this deterioration can be attributed to a decrease in active nucleation site density caused by the decrease in contact angle (θ) between the fluid and heater surface, as observed in several studies [54,75,85]. This effect can be explained in the following equation suggested by Wang and Dhir [103]: 6 (2)…”

“…On the other hand, to meet the heat dissipation requirements of next-generation power electronics and devices, further development of advanced spray cooling is urgently needed. There are multiple ways to improve the spray cooling performance, including selection and alteration of the working fluid [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57], optimization of spray parameters [58][59][60][61][62] or systems [17,[63][64][65][66][67][68][69][70][71][72][73][74][75][76], and surface engineering. The first two methods are based on the fluid side, which is limited in affecting liquid-wall interactions.…”

The rapid development of electronics, energy and propulsion systems has led us to the point where their performances are limited by cooling capacities. Heat fluxes of 10~100, even over 1,000 W/cm2 need to be dissipated with minimum coolant flow rate in next-generation power electronics. Spray cooling is a high heat flux, uniform and efficient cooling technique proven effective in various applications. However, its cooling capacity and efficiency need to be further improved to meet next-generation ultrahigh-power applications. Engineering of surface properties and structures can fundamentally affect the liquid-wall interactions, thus becoming the most promising way to enhance spray cooling. However, the unclear mechanisms of surface-enhanced spray cooling cause lack of guiding principles for surface design. Here, progress in spray cooling on surfaces with structures of different scales are reviewed and their performances evaluated and compared. Spray cooling can achieve critical heat flux (CHF) above 945 W/cm2 and heat transfer coefficient (HTC) up to 57 W/cm2K on structured surfaces for pressurized nozzle and CHF and HTC up to 1250 W/cm2 and 250 W/cm2K, respectively, on a smooth surface with the assistance of secondary gas flow. CHF enhancement of 110% was achieved on hybrid micro- and nanostructured surfaces. A clear map of enhancement mechanisms is proposed after analysis. Some future concerns are also proposed. This work helps the understanding and design of engineered surfaces in spray cooling and provides insights for interdisciplinary applications of heat transfer and advanced engineering materials.

“…To investigate nanofluids in phase change heat transfer for potential enhancement, extensive research has also been performed. Thermal management systems such as microelectronics [4,5], HVAC systems [6], automotive industry [7,8], solar collectors [9,10], cooling system in electronics [11,12], and nuclear reactors [13,14] use nanofluids to improve heat transfer and thermal efficiency. These are used in light water reactors due to their capability to manage strategy in severe accidental conditions to enhance the in-vessel retention capability [15].…”

Nanofluids are suspensions of nanoparticles with small concentration spread in base fluids such as water, oil and ethylene glycol. Nanofluid boiling is an important research area which provides many chances to explore new frontiers but also poses great challenges. Over the last decade, various studies have been carried out on pool boiling of nanofluids for the enhancement of critical heat flux which is otherwise limited by the use of base fluids. Several efforts have been made in the literature on nanofluid boiling, however, data on the boiling heat transfer coefficient and the critical heat flux have been unpredictable. Current study is a review of the status of research work on effects of nanofluids on heat transfer coefficient and critical heat flux. An emphasis is put in a review form on the recent progresses in nanofluid heat transfer coefficient and critical heat flux of pool boiling. This study also focuses on advancements in nanofluids, their properties and various parameters affecting boiling critical heat flux and heat transfer coefficient. At the end correlations used by different researchers to find out the critical heat flux and heat transfer coefficient are listed.
