Usage of phase change materials' (PCMs) latent heat has been investigated as a promising method for thermal energy storage applications. However, one of the most common disadvantages of using latent heat thermal energy storage (LHTES) is the low thermal conductivity of PCMs. This issue affects the rate of energy storage (charging/discharging) in PCMs. Many researchers have proposed different methods to cope with this problem in thermal energy storage. In this paper, a tubular heat pipe as a super heat conductor to increase the charging/discharging rate was investigated. The temperature of PCM, liquid fraction observations, and charging and discharging rates are reported. Heat pipe effectiveness was defined and used to quantify the relative performance of heat pipe-assisted PCM storage systems. Both experimental and numerical investigations were performed to determine the efficiency of the system in thermal storage enhancement. The proposed system in the charging/discharging process significantly improved the energy transfer between a water bath and the PCM in the working temperature range of 50 & DEG;C to 70 & DEG;C.

Experimental analysis of energy storage device using phase change material integrated with a milk storage system Nıma, Bonyadı; Somek, Suleyman Kazım; C Cıhan, Ozalevlı; Baker, Derek Keıth; Tarı, İlker (null; 2015-08-12) Phase change materials (PCMs) have the advantage of storing latent heat at constant temperature and can possess higher energy storage densities in comparison to materials storing sensible heat. Due to these features, latent heat Thermal Energy Storage (TES) devices using PCMs are widely used to store heat in thermal systems. The aim of this study is to experimentally investigate the performance of water PCM in an improved milk storage cooling cycle integrated with a TES device. In this prototype, water is u...
Effect of bypassing the heat transfer fluid on charging in a latent thermal energy storage unit Baghaei Oskouei, Seyedmohsen; Bayer, Özgür (2023-06-01) Horizontal latent thermal energy storage (LTES) systems that use phase change materials (PCMs) are popular and effective methods of alleviating the intermittency of renewable energy sources. The main issue of PCMs is their low thermal conductivity, resulting in long charging times and slow response. In this investigation, a novel method to overcome this issue is proposed by designing bypassing tubes that redirect the flow of heat transfer fluid to the bottom of the horizontal LTES tank, where the melting ra...
A novel cascade latent heat thermal energy storage system consisting of erythritol and paraffin wax for deep recovery of medium-temperature industrial waste heat Yang, Sheng; Shao, Xue-Feng; Luo, Jia-Hao; Baghaei Oskouei, Seyedmohsen; Bayer, Özgür; Fan, Li-Wu (2023-02-15) Recovering medium-temperature (e.g., 150–180 °C) industrial waste heat through latent heat thermal energy storage (LHTES) can effectively attenuate the consumption of fossil fuels. However, the LHTES system containing a single medium-temperature phase change material (PCM), e.g., erythritol, cannot absorb the part of heat below the PCM's melting point (∼118 °C) during the charging process. Meanwhile, a single low-temperature PCM, e.g., paraffin wax, is unable to supply a significant amount of heat at temper...
Implementation of metal-based microchannel heat exchangers in a microrefrigeration cycle, and numerical and experimental investigation of surface roughness effects on flow boiling Jafari Khousheh Mehr, Rahim; Okutucu Özyurt, Hanife Tuba; Ünver, Hakkı Özgür; Department of Mechanical Engineering (2015) A microscale vapor compression refrigeration cycle has been constructed for possible application in the thermal management of compact electronic components. The micro-evaporator and micro-condenser components have been fabricated using wire electron discharge machining and micromilling, respectively. Three microevaporators have been manufactured with different surface roughness for the experimental and numerical investigation of roughness effect on nucleate flow boiling in microchannels. In the numerical pa...
Enhancement of hydrogen storage capacity of multi-walled carbon nanotubes with palladium doping prepared through supercritical CO2 deposition method ERÜNAL, EBRU; Ulusal, Fatma; ASLAN, MUSTAFA YASİN; GÜZEL, BİLGEHAN; Üner, Deniz (Elsevier BV, 2018-06-07) Pd doped Multi-Walled Carbon Nanotubes were prepared via supercritical carbon dioxide deposition method in order to enhance the hydrogen uptake capacity of carbon nanotubes at ambient conditions. A new bipyridyl precursor that enables reduction at moderate conditions was used during preparation of the sample. Both XRD analyses and TEM images confirmed that average Pd nanoparticle size distribution was around 10 nm. Hydrogen adsorption and desorption experiments at room temperature with very low pressures (0...
