Simultaneous energy storage and recovery in the triplex-tube heat exchanger with PCM, copper fins and Al2O3 nanoparticles
TL;DR: In this paper, a triplex-tube heat exchanger (TTHX) with phase change materials (PCMs) has been found to be a very efficient energy storage application for this purpose, but the low thermal conductivity of PCMs makes them unable to give the desired response for storage and recovery.

Investigation of the effect of inclination angle on the melting enhancement of phase change material in finned latent heat thermal storage units
Ramin Karami,Babak Kamkari +1 more
TL;DR: In this article, the effect of the inclination angle of finned enclosures on the development of buoyancy-driven convection flows is investigated, and the results showed that the melting time reduces by decreasing the inclination angles of the enclosure due to the intensification of the natural convection flow and increase in the number of vortices in the liquid PCM.

Solidification acceleration in a triplex-tube latent heat thermal energy storage system using V-shaped fin and nano-enhanced phase change material
TL;DR: In this paper, a triplex-tube Latent Heat Thermal Energy Storage System (LHTESS) by employing V-shaped fins and nanoparticles as enhancement approaches was used to balance the energy supply and requirement.

Investigation of phase change material solidification process in a LHTESS in the presence of fins with variable thickness and hybrid nanoparticles
TL;DR: In this paper, the effect of fin geometric parameters on the solidification acceleration was analyzed, and the best fin configuration was determined using Response Surface Method (RSM) optimization, which showed that employing optimized fin results in higher solid fraction rate in comparison with dispersing hybrid nanoparticles into the PCM.

Advanced/hybrid thermal energy storage technology: material, cycle, system and perspective
TL;DR: Each advanced/hybrid TES technology has a certain improvement over basic TES, such as increasing the energy storage density or energy storage efficiency, reducing the charging temperature, enhancing the thermal conductivity of the sorbents, stabilizing the discharging temperature, or improving the performance of the integrated systems.

Factorial sampling plans for preliminary computational experiments
TL;DR: The proposed experimental plans are composed of individually randomized one-factor-at-a-time designs, and data analysis is based on the resulting random sample of observed elementary effects, those changes in an output due solely to changes in a particular input.

A fixed grid numerical modelling methodology for convection-diffusion mushy region phase-change problems
Vaughan R Voller,C. Prakash +1 more
TL;DR: In this article, an enthalpy formulation based fixed grid methodology is developed for the numerical solution of convection-diffusion controlled mushy region phase-change problems, where the basic feature of the proposed method lies in the representation of the latent heat of evolution, and of the flow in the solid-liquid mushy zone, by suitably chosen sources.

A review of materials, heat transfer and phase change problem formulation for latent heat thermal energy storage systems (LHTESS)
TL;DR: In this paper, the phase change problem has been formulated using pure conduction approach but the problem has moved to a different level of complexity with added convection in the melt being accounted for, which makes it difficult for comparison to be made to assess the suitability of PCMs to particular applications.
