High temperature thermal energy storage an experimental study

Heat Transfer Enhancement Techniques for Solar Air Collector Hater: Review

“…Results illustrated that melting time has 36-41% shorter in the three phase change materials capsule than that in the single phase change materials capsule. The evaluation of the thermal efficiency of a thermal storage system using three phase change materials and filled in a number of cylindrical capsules with air flowing across them has been performed by (Adinberg et al, 1999;Shabgard et al, 2010). A similar conclusion (Jegadheeswaran and Pohekar, 2009;Wang et al, 2001) showed that the performance of a thermal porous storage system focusing five phase change materials was from 12% to 25% higher than that of single phase change materials system.…”

CSP Gen3: Liquid-Phase Pathway to SunShot

“…The rotary action of triple-offset butterfly valves has been shown to place less stress on the packing in comparison to translating stem [41]. A financial argument could be made to support the use of this style of valve for large bore isolation applications, due to the significant difference in capital cost for large bore globe valves with a bellows seal.…”

Heat transfer enhancement and applications of thermal energy storage techniques on solar air collectors: A review

“…Results found that in the threephase change materials capsule, melting time was 36-41 percent smaller than the materials capsule for single-phase change. The thermal performance measurement of a thermal storage device using three-phase shift materials and loaded with air streaming through a number of cylindrical capsules was carried out by [75][76][77]. The findings revealed that the rate of heat transfer in all charging and discharge processes improved by approximately 10 percent compared to units including materials with one phase transition.…”
