“…A similar analysis of a finned absorber plate was given in by Josyula et al [77]. Reyes et al [78] described the use of a combination of two different paraffins with different melting temperatures to enhance the discharge efficiency of a solar thermal system. They found that a combination of two materials is beneficial if the lower melting temperature material is placed first.…”

Demand for domestic hot water and heating is rarely perfectly concurrent with solar irradiation, which means that collectors can overheat in periods of high incident radiation and low demand. Phase change materials have been used as energy storage in space heating applications to absorbs excess heat during low demand periods for use in peak demand periods. This paper reviews the current state of research on the possibility of application of such materials as energy storage for solar collectors, in order to avoid collector overheating. Finally, various materials were evaluated and ranked for this application based on required properties and price. An example model of such materials being applied in a typical family house domestic hot water solar system is also provided.

“…[30] paraffin as a heat storage material for solar heat storage system the influence of porosity of packed bed on time for complete solidification is not so significant. [32] analyzed the addition of aluminum foil from waste material to increase the thermal conductivity of the paraffin storage material using paraffin wax with 8% w/w of aluminum foils and found the thermal conductivity increased up to 0.63 W/mK. [24] a suitable proportion of expanded graphite (EG) into the paraffin can enhance the heat transfer rate, thus improve the thermal efficiency of the whole heat storage system.…”

“…[33] proved that the addition of TiO2 The addition of additive material can be considered as an easy and cheap method to improve paraffin performance as thermal energy storage. For lower temperature application, the addition of sensible heat material like water, rock and sand considered as the easiest and cheapest way to enhancing the paraffin performance [36][37] [32]. The recommended working area for sensible-PCM as thermal storage in the solid-liquid transition is known better than the liquidvapor phase and the solid-solid phase [38] [39][40] [41].…”

Thermal energy storage has a good opportunity to be applied in engineering field, especially for low temperature application like automotive thermal management system. Paraffinic is a better option and considered as a good phase change material with main advantages like economically feasible, non-corrosive and safe. The main drawbacks of paraffinic system are low thermal conductivity and supercooling effect. The effort to improve the performance for paraffinic system is by g sensible material. Considering the spread of volcano in Indonesia, it can be used as sensible material for paraffinic system. The aim of the research is to examine the volcanic ash characteristic and the effect of sand addition on the paraffinic system. a standardized approach for sand examination is done and the effect of the hybrid PCM (90% paraffin and 10% volcanic ash mass ratio) are studied. The overall performance of hybrid PCM is better than pure paraffin where the vapor point of hybrid PCM is increased and there is no supercooling phenomenon observed.

“…The World Bank group helps to choose the site that needed by many specialists to avoid subjective biases, usually wishing on rough estimations wherever the topography wasn't absolutely. Therefore, this study proposes a procedure methodology that estimates the potential of solar energy for prioritizing and choosing sites for power production from the PV system exploitation in public offered digital numerical maps (Reyes et al, 2019;Shahid, Kalhoro, Ara, Bano & Perween, 2019;Kalhoro et al, 2019;).…”

Intelligent disaster management and green computing constitute rapidly expanding research areas spanning the fields of soft computing, environmental technologies, computer science, engineering and information management. The explosion of Open and Big Data have given rise to new opportunities for understanding and solving formerly intractable environmental and disaster management challenges. The use of Big Data has now been mainstraimed into all recent trends in computing and engineering as well different disciplinary fields such as computational biology, disaster response, healthcare, social networks, finance, transportation and telecommunications. This special issue provides a unique and powerful vehicle for disseminating the latest research dealing with intelligent disaster management and green computing research, development, applications and its intelligence. The rise of Big and Open Data-and the ease with which scientists, communities, thought leaders and decision makers can access it-redefining how governments, civil society and the private sector operate. References to Big and Open Data have grown exponentially over in the past several years, and examples of big data abound, giving rise to a new philosophy of 'open-source environmental governance and disaster management', that promotes a linkage between the principles of the disaster science, green computing and open-source and open-content movements.This set of distinguished eighteen papers strengthens interdisciplinary linkages between the fields of green computing and disaster science investigates current gaps in environmental technologies and and the opening of new research directions in the era of Big and Open Data era. Rather than separating the engineering technologies from its 'real world' impact, those contributing to this special issue have demonstrated attention to the issues of societal resilience, environmental governance and disaster risk reduction and that their work informs. Accordingly, this special issue helps 3C Tecnología. Glosas de innovación aplicadas a la pyme.
