The aim has been to build the equivalent electric circuit of the mixed solar drying facility and investigate the space and time variabilities of temperature transfer in a solar drying system.The balance equations modelling the physical elements are approximated iteratively using the finite difference method. The results obtained indicate that the proposed two-dimensional predictions based on sinusoidal approximation of solar radiation and air temperature inputs adequately describe both collector and dryer temperature profiles. The influences of various parameters such as the space resolution, the mass flow rate, the average temperature and solar radiation inputs have been investigated and discussed. The numerical simulations show that the temperature of each element of the drying system is not uniform and varies considerably with the space and time nodes, and therefore increases gradually from the first-node of the macroscopic drying flow to the end-node.","PeriodicalId":213184,"journal":{"name":"American Journal of Energy Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130221168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photovoltaic (PV) cell is the fundamental unit in the power conversion of the solar system. When the PV cells are exposed to partial shading as a result of a multitude of environmental conditions, the performance of the solar PV module is remarkably affected in terms of the efficiency of the system. In many cases, the PV arrays are shadowed, whether completely or partially, by passing clouds, neighboring buildings and towers, trees, or the shadow of one solar array falling on another. This study investigates the effects of partial shading on energy output of different configurations of solar PV modules. In this study, three different solar PV configurations are investigated: 1) Series 2) Parallel, and 3) Series-Parallel. All the considered PV configurations are analyzed using several possible scenarios of shading in order to evaluate their performances and to find a configuration that is comparatively less susceptible to electrical mismatches due to shadow problems. Owing to the practical difficulty of conducting experiments on varied array sizes, the proposed model also includes a general model of a PV module, which was implemented on MATLAB/Simulink and has been developed for any required array size, configuration and different shading patterns. This model is simple and especially useful to calculate the actual performances of the PV modules under various operating conditions.","PeriodicalId":213184,"journal":{"name":"American Journal of Energy Research","volume":"23 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125781177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, approaches introducing reduced energy processing of textiles in association with the standard energy management practices would be in obvious demand. Energy management standard is particularly desired for energy- intensive industrial sectors. Textile finishing organizations significantly depends upon the continual energy supply from fiber production to finished fabric. Textile processing areas that heavily consume water and electricity can be significantly improved in terms of reduced energy utilization and minimum energy loses through exercising improved housekeeping and standard management practices. It was perceived that ISO 50001 standard will provide management guideline and approaches to the textile sector organizations leading to an increased efficiency, reduced cost through less energy consumption, and improved energy performance. Any scientific information and data on hot air, heat, steam and processed water recycling available in literature would indeed be beneficial to enhance textile processing and finishing industry in the utilization of energy management policy, performance and efficiency measures, physical structure. The important factors that would be influenced by the energy management standard in textile finishing, ranging over fiber processing, pre- treatments, dyeing, printing, and special effects, are identified for improvement and discussed in this paper.","PeriodicalId":213184,"journal":{"name":"American Journal of Energy Research","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132104666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
