Phase Change Slurries for Cooling and Storage: An Overview of Research Trends and Gaps

Abstract

Phase change slurries (PCSs) have great potential as both a heat transfer fluid and an energy storage medium for cooling processes, cold energy storage, and cold energy transportation due to desirable thermophysical properties. One of the major benefits of PCSs compared to pure phase change materials is their fluidity, thus making them cooled or heated by a heat exchanger, pumped through pipes, discharged, and stored directly in a thermal energy storage tank. The use of encapsulated phase change slurries and gas hydrate slurry has thus attracted considerable interest as reflected in the literature with a rising number of publications and institutions involved in the area. The use of bibliometric techniques has found a recent interest in the literature to define the progress of different scientific topics and inspire researchers to identify novelties. In this paper, bibliometric analysis and a detailed systematic review are carried out to show the state-of-the-art development of PCSs for cooling applications. Research gaps and hotspots are identified to help define future perspectives on this topic.

An Heat Transfer Coefficient and Pressure Characteristics in a Copper Pipe Flow System: A Preliminary study Utilizing an EG/Water Mixture

“…The heat transfer coefficient is an essential factor that measures the rate at which heat is transferred across a surface and the medium of fluid [4,5]. It denotes the capacity of the fluid to conduct heat and is an important factor for assessing the effectiveness of heat transfer processes [6,7]. The heat transfer coefficient is influenced by a variety of factors, including fluid attributes, conditions of flow, and surface characteristics [8,9].…”

The Heat Transfer Coefficient in a Copper Pipe Flow System Using a 40/60 Volume Ratio Ethylene Glycol/Water (EG/H2O) Blended Fluid

“…The heat transfer coefficient is a fundamental parameter that quantifies the rate of heat transfer between a surface and a fluid medium [3] [4]. It represents the ability of a fluid to conduct heat and is a crucial factor in determining the efficiency of heat transfer processes [5] [6]. The heat transfer coefficient depends on several factors, including the physical properties of the fluid, the flow conditions, and the nature of the surface [7] [8].…”
