“…Faghiri et al [65] experimentally studied the drop impact dynamics for direct-contact heat exchange between an impinging intermediate boiling fluid droplet and molten PCM for LHTES. Selimefendigil and Öztop [66] numerically analyzed convective heat transfer enhancement of nano-enhanced fluid with magnetic field and multi-jet impingement on a micro-encapsulated PCM-packed bed system. Based on review of the literature, the use of jet impingement has yet to be implemented on traditional LHTES systems.…”

Renewable energy resources require energy storage techniques to curb problems with intermittency. One potential solution is the use of phase change materials (PCMs) in latent heat thermal energy storage (LHTES) systems. Despite the high energy storage density of PCMs, their thermal response rate is restricted by low thermal conductivity. The topic of heat transfer enhancement techniques for increasing thermal performance of LHTES systems has mainly focused on passive heat transfer enhancement techniques with less attention towards active methods. Active heat transfer enhancement techniques require external power supplied to the system. In this paper, recent advances in active heat transfer enhancement techniques within LHTES systems are reviewed, including mechanical aids, vibration, jet impingement, injection, and external fields. The pertinent findings related to the field are summarized in relation to the charging and discharging processes of PCMs. Suggestions for future research are proposed, and the importance of additional energy input for storage is discussed.

Purpose This paper aims to study the fluid flow and heat transfer within the Casson nanofluid confined between disk and cone both rotating with distinct velocities. For a comprehensive investigation, two distinct nano-size particles, namely, silicon dioxide and silicon carbide, are submerged in ethanol taken as the base fluid. Design/methodology/approach This paper explores the disk and cone contraption mostly encountered for viscosity measurement in various industrial applications such as lubrication industry, hydraulic brakes, pharmaceutical industry, petroleum and gas industry and chemical industry. Findings It is worth mentioning here that the radially varying temperature profile at the disk surface is taken into the account. The effect of prominent emerging parameters on velocity fields and temperature distribution are studied graphically, while bar graphs are drawn to examine the physical quantities of industrial interest such as surface drag force and heat transfer rate at disk and cone. Originality/value To the best of the authors’ knowledge, no study in literature exists that discusses the thermal enhancement of nano-fluidic transport confined between disk and cone both rotating with distinct angular velocities with heat transfer.

The ever‐growing applications of high‐power chips have driven research efforts to enhance the performance of their active cooling modules. This study proposes a simple tweak of the cooling module's ports for lower thermal resistance. A dual‐inlet single‐outlet (CP2) jet impingement cold plate (JICP), a dual‐inlet dual‐outlet (CP3) JICP, and a single‐inlet dual‐outlet (CP4) JICP were assessed computationally and benchmarked against a single‐inlet single‐outlet JICP (CP1) at the same area ratio (AR) and average diameter (Davg) of inlet and outlet ports. The results show that the pressure losses inflate by up to 4.67 folds when using CP3 with AR = 5/3 and Davg = 3.0 mm. Yet, this design also shows the largest Nusselt number and the lowest outlet water temperature, module body temperature, average temperature of the target surface, and thermal resistance (0.07415 K/W). The thermal resistance is reduced by 34.13% using CP3 at AR = 3/5 and Davg = 6.0 mm. The temperature uniformity index was boosted to 97.5%. These enhancements are attributed to the shorter and symmetric flow path, the shorter residence time of water within the JICP, and the direct heat diffusion by the walls of the lower chamber.
