A scientometric analysis about eSports publications from 2007 to 2017 was carried out. HistCite was used to analyze the data collected from Web of Science during the period mentioned. The results suggest that eSports research has increased during the 11 years of study; the country with the highest number of publications was the United States of America, with eight institutions predominant in the number of publications. Most of the articles and the highest local score of total citations come from countries where eSports are considered sport; the top three journals with the most publications were International Journal of Gaming and Computer-Mediated Simulations, Games and Culture and Psychology of Sport and Exercise, where the top three journals with the highest TLCS are Games and Culture, New Media & Society and Computers in Human Behavior.
In this work the advantage of the use and implementation of ORC heat recovery systems for low temperature (<230°C) exhaust gases from a natural gas engine was studied. Different organic fluids and working conditions were analyzed in order to determine the best decision in terms of energy efficiency and exergética refers to criteria such as cost, environmental impact, flammability toxicity among others. It was found that the performance for the different configurations is closely linked to the evaporation pressure, reaching an electrical power of 120kWe (10%) for the simple configuration. The working fluid with the highest performance was acetone regardless of the configuration analyzed. Simultaneously, an international and national context was created in different fields for heat recovery systems.
The way to evaluate a device in charge of heat transfer under certain working conditions is through the study of the global coefficient of heat transfer, it was carried out using a test bench that includes the base unit where the heating and movement of water is carried out and a unit where the heat exchange is carried out connected by means of flexible tubes and using the fundamental equations that are required, the results obtained were respectively the global transfer coefficient for both fluids of work with their respective Nusselt number, finally it is observed that the relationships between other models for plate exchangers, the comparative error is very large (40%) and to have more concise results. the scale factor must be taken into account.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
