Accelerated melting of PCM in energy storage systems via novel configuration of fins in the triplex-tube heat exchanger
Published in International Journal of Heat and Mass Transfer
Thermal energy storage with Phase Change Materials (PCMs) can be used to fill the gap between energy supply and demand. The main reason preventing their widespread application is the low thermal conductivity of PCMs which makes the systems to have slow energy storage and recovery rates. This study achieved better PCM melting rate with novel fin con...
Hybrid heat transfer enhancement for latent-heat thermal energy storage systems: A review
Published in International Journal of Heat and Mass Transfer
The potential of phase-change materials (PCMs) for application in the fields of thermal energy storage and thermal management is well recognized, due to their remarkable energy storage density and negligible temperature variation during operation. However, these materials do face the primary challenge of low thermal conductivity which necessitates ...
Simultaneous energy storage and recovery in the triplex-tube heat exchanger with PCM, copper fins and Al2O3 nanoparticle...
Published in Energy Conversion and Management
The intermittent nature of renewables such as solar and wind necessitates integration with energy-storage to enable realistic applications. The triplex-tube heat exchanger (TTHX) with phase change materials (PCMs) has been found to be a very efficient energy storage application for this purpose. However, the low thermal conductivity of PCMs used ma...
Solidification enhancement with multiple PCMs, cascaded metal foam and nanoparticles in the shell-and-tube energy storag...
Published in Applied Energy
The thermal response of the shell-and-tube energy storage system consisting of multiple segments holding separate phase-change materials (PCMs) of different melting points was studied. Nanoparticles in PCM of 5% volume fraction with cascaded (multiple-segment) metal foam of average porosity 0.95 were applied the heat-transfer enhancement. A simulat...
Performance of wind turbines at three sites in Iraq
Published in International Journal of Renewable Energy Research-IJRER
Matching between wind site characteristics and wind turbine characteristics for three selected sites in Iraq was carried out. To date, site-turbine matching for potential wind power application in Iraq has not yet been well reported on. Thus, in this study, five years’ wind speed data for sites located in Baghdad (23.26N, 44.23E), Nasiriyah (31.02N...
