Phase change material based latent heat energy storage systems have emerged as a promising option to effectively store thermal energy. Generally, paraffin wax is used as the most common phase change material for low to medium temperature storage applications because it has a large latent heat and low cost besides being stable, nontoxic and non-corrosive. The performance of paraffin wax based latent heat energy storage systems (LHESS) is limited by its poor thermal conductivity. In this paper, the previous experimental and theoretical research studies on LHESS using paraffin wax as phase change material with different performance enhancement techniques are reviewed. Further, research works related to dispersing different kind of nanoparticles in paraffin wax for the enhancement of its thermal conductivity are comprehensively reviewed with respect to synthesis, characterization and thermophysical properties of the nanoenhanced phase change material.

There has been a significant increase in the number of these events since the second half of the 20th century. From the meteorological observations in the period 1950-2014 in the regions of Valencia and Murcia, in the central sector of the Spanish Mediterranean coast, this work analyses the evolution of the number of tropical nights, the length of the episodes, and their frequency. We also discuss the relationship of the number of tropical nights with the increase of the Mediterranean Sea surface temperatures in the sectors of the Algerian and Balearic Seas, as

Buongiorno's nanofluid model has been considered with nanoparticle electrification. A similarity transformation is introduced to reduce the governing non-linear partial differential equation into coupled ordinary differential equations which are then solved numerically using bvp4c function of MATLAB software. Validation of the result has been made by comparing the Subhashree Panda, Ashok Misra and Saroj Kumar Mishra 364 present results with the results obtained from the previous studies. The effects of angle of inclination, buoyancy ratio parameter, Brownian motion, thermophoresis and electric field on different flow parameters are depicted through figures and tables. It is observed that the impact of nanoparticle electrification is to enhance the non-dimensional skin friction coefficient as well as both heat and mass transfer rates in active control cases.
