Experimental analysis of a microencapsulated PCM slurry as thermal storage system and as heat transfer fluid in laminar flow

Design of a low-temperature solar heating system based on a slurry Phase Change Material (PCS)

“…In fact, thanks to the lower working temperature, the mPCS storage tank is expected to be more efficient than traditional solar thermal systems. On the other hand, the pressure drops caused by the mPCS will be higher than those of the water [74][75][76][77][78]. Since an increase in the pressure drops corresponds to an increase in the pump energy consumption, pressure drops need to be limited in order to avoid significantly affecting the benefits derived from the improved thermal efficiency, and the energy demand of the auxiliaries must be investigated in detail (Fig.…”

Experimental study on the influence of nanoparticle PCM slurry for high temperature on convective heat transfer and energetic performance in a circular tube under imposed heat flux

“…To check if the use of a nanofluid is more beneficial from an energy point of view than the use of the base fluid, one has to define a performance energetic criterion (PEC). In the literature [4,5], several studies have used a criterion: If this ratio is less than 1, using a nanofluid is not recommended from an energy point of view.…”

Building Integrated Solar Thermal (BIST) Technologies and Their Applications: A Review of Structural Design and Architectural Integration

“…PCM, because of its higher energy storage density and thermostatic fusion, is particularly attractive in the BIST application due to the two-phase heat transfer process [14]. In recent years, a new technique has been proposed to use the PCM slurry as pumpable heat transfer fluids and as heat storage systems [15][16][17]. Through microencapsulating and isolating PCM from its surroundings and the carrier fluid, the PCM is less likely to hamper the heat transfer process [18].…”
