“…With the increasing heat flux density required in today's heat transfer facilities [16] , "Complex enhanced he at transfer" means that two or more technologies are used to enhance heat transfer. This so-called "third generat ion" heat transfer technology has greatly improved the heat transfer efficiency [17] .…”

Studies have shown that ultrasonic waves can enhance heat transfer in Pulsating Heat Pipes, it also enhances the heat storage of Phase Change Materials, however, there are few studies on ultrasonic composite Pulsating Heat Pipes reinforced phase change material heat storage. In this paper, a phase change material heat storage device under ultrasonic field is designed, and the enhanced heat transfer performance of ultrasonic composite Pulsating Heat Pipes is studied and analyzed. Experimentally observed the change of heat storage efficiency of the heat storage device caused by ultrasonic wave at different power and different positions. The results show that : under the same ultrasonic (28KHz)frequency, after applying power of 50W、100W and 120W ultrasonic fields on one side of the heat storage device, the heat storage efficiency increased by 55.6%、 57.5% and 67.1% respectively ; the heat transfer coefficients under power of 50W and 120W ultrasonic fields are respectively Increased by 6.1% and 12.6% ; after applying 50W、100W and 120W ultrasonic fields on both side of the heat storage device, the heat storage efficiency increased by 44.5% 、 60.4% and 73.4% respectively, and the heat storage efficiency increased non-linearly. Then the heat storage process was analyzed, and it was found that the heat transfer coefficient fluctuated, and the heat transfer coefficient reached the maximum when the phase transition temperature was just reached. In addition, it was found that ultrasonic waves combined with Pulsating Heat Pipes enhanced heat transfer, which significantly shortened the start-up time of pulsating heat pipes, and verified the enhanced heat transfer of supercooled boiling of Pulsating Heat Pipes under ultrasonic fields; the research results can be used to design closed phase change thermal energy storage units, would provide useful inspiration for further development and application of Pulsating Heat Pipes and Phase Change Materials with ultrasonic.

“…One of the primitive and advanced techniques to treat such waters is done by using solar stills. The distilling plants incorporating solar energy are comparatively economical, low‐technology systems, especially useful for the process industries and agriculture sector 6,7 . Molten salt reactors (MSRs) are a type of advanced nuclear reactor that uses a liquid fuel consisting of a mixture of molten salts as both the coolant and the fuel carrier.…”

Saltwater or brackish water is used as a coolant in most industries. Therefore, understanding the heat transfer processes and hydrodynamics during the natural convection in saline water is crucial for enhancing the efficiency of a heat exchanger. This study elaborates on the natural convection heat transfer in saline water under atmospheric conditions. A DC power supply is used to regulate the power given to the heater in a liquid pool for thermal analysis. The pool liquid comprises solutions with varying salinity from 0%, 0.2%, 0.5%, and 2%. The effect of varying salinity on the heat transfer coefficient and the thermal aspects encountered during the desalination process is analyzed. The temperature distribution across the surface

“…HTE or augmentation or intensification means the improvement of thermal performance of any heat transfer and mass process, heat exchanging medium, thermal component, heat transfer device, heating/cooling equipment, thermal energy technologies, thermodynamic system. Following the reviews conducted on HTE, thermal energy and process intensification literature in 2019 and 2020 (Guo et al, 2020;Guo et al, 2021), the present review continues to circumscribe HTE, thermal energy, process and transport intensification papers published in archival journals in English language in the single year 2021. Consideration has been given to the research regarding HTE, thermal energy and process intensification and the publication amount is huge, thus, selection is unavoidable.…”
