Solar energy storage and release application of water-phase change material- (SnO2-TaC) and (SnO2–SiC) nanoparticles system

Abstract

<p>The thermal energy storage and release application of water- phase change material- (SnO<sub>2</sub>-TaC) and (SnO<sub>2</sub>–SiC) nanoparticles system has been investigated for cooling and heating applications. The water - polyethylene glycolwith (SnO<sub>2</sub>-TaC) and (SnO<sub>2</sub>–SiC) nanoparticles have been used. The results showed that the melting and solidification times for storage and release of thermal energy of water - polyethylene glycoldecrease with increase in(SnO<sub>2</sub>-TaC) and (SnO<sub>2</sub>–SiC) nanoparticles concentrations. The melting and solidification times decrease with increasing of TaC nanoparticles concentrations to water-polyethylene glycol/SnO<sub>2</sub>nanofluidand SiC nanoparticles concentrations to water-polyethylene glycol/SnO<sub>2</sub>nanofluid.<strong></strong></p>

Preparation of Nanofluids from Inorganic Nanostructures Doped PEG: Characteristics and Energy Storage Applications

“…As the concentration of ZrO 2 /SiC nanoparticles increases, the melting time reduces. PEG/ZrO 2 /SiC-H 2 O nanofluids' reduced melting time for energy storage applications is owing to improved thermal conductivity, which increases heat transfer [24][25][26][27][28][29][30][31][32]. When the concentration of ZrO 2 /SiC NPs increases from 3 weight percent to 12 weight percent within 15 minutes, the increment in melting time reaches 51.2%.…”

“…The electrical, magnetic, mechanical, optical, and thermal properties of nanofillers can be enhanced by incorporating organic and inorganic materials into their structures. Nanofillers can be used in a wide range of applications, such as the production of tissue, filters, catalysis, scaffolds, wound dressing, and sensors [5][6][7][8][9][10][11].…”

Preparation and Properties of ZrO2/SiC-H2O Nanofluids to Use for Energy Storage Application

“…When there was a greater concentration of ZrO 2 /SiC nanoparticles, the melting time was cut down significantly. Increases in thermal conductivity lead to increases in heat transmission, which in turn lead to reductions in melting times for ZrO 2 /SiC-H 2 O nanofluids that are used for energy storage [30][31][32][33][34][35]. The decrease in melting time reached 41.2% when the concentration of ZrO 2 /SiC NPs rose from 0.3 gm/L to 1.2gm/L after 15 minutes.…”

“…This is due to the fact that the thermal conductivity of a solid metal is higher than that of a base fluid. For a good number of years now [1][2][3][4][5][6][7][8][9][10], people have been aware of the fact that the suspension of solid particles, such as those measuring millimeters or micrometers in size, may increase the thermal conductivity of typical fluids. [Such particles] The thermophysical parameters of a nanofluid, including its density, viscosity, thermal conductivity, and specific heat capacity, have a significant impact on the flow and heat transfer performance of the nanofluid.…”

Experimental Investigation on Thermal Performance of Solar Air Heater using Nano-PCM

“…Lin et al, [12] conducted a practical study that included the use of pure paraffin wax in the process of storing thermal energy to heat closed buildings, which effectively affected the process of storing and rationalizing solar energy consumption. Air heating systems can be obtained using a lot of designs based on solar energy storage using paraffin wax and its mixtures [13][14][15].…”
