This type of low-level energy source permanently causes heat emissions, global warming, as well as climatic changes in which our world lives today. Re-exploitation of this type of energy contributes to the production of the required energy for various industrial purposes, as well as the production of electrical power. In this paper, the ORC is integrated with the Steam Rankine Cycle (SRC) as a bottoming cycle which can be called, the Binary Rankine Cycle (BRC) to generate 5MW net power. As there are two fluids used in the system, water in the topping cycle and organic fluid in the bottoming cycle. The BRC may utilize solar energy as a heating source. With the increasing need for efficient and low-cost energy solutions, it is essential to understand the thermal performance of a system built in different climates. The performance of the system is carried out and compared with different organic fluids R134a, R245fa, and R1234yf at different steam turbine inlet temperatures, pressures, and back pressures. The study reveals that the R245fa BRC has the best performance followed by the R134af BRC and then the R1234yf BRC. Also, the study aimed to determine the best solar collector area in Aswan","PeriodicalId":161226,"journal":{"name":"Engineering Research Journal","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126888435","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 specimens were divided into two groups according to two cement grades used. Each of the two Groups consisted of 9 concrete cylinders, eight of which were CFRP fully or partially confined. The last cylinder of each group was without CFRP wrapping, used as control specimen for comparison. The used CFRP strips were from two different Sources (1) and (2) applied to cylinder surface using either one of two epoxy resin Sources (a) and (b). Two systems of the application of CFRP with epoxy resin were adopted. System (1) using CFRP Source (1) with epoxy resin Source (a). System (2) using CFRP Source (2) with epoxy resin Source (b). Each application system was adopted for 8 cylinders using each of the two cement grades. Four schemes of CFRP wrapping, either fully or partially confined, were used. Based on obtained test results, conclusions are presented regarding the parameters affecting the ultimate compressive load of tested concrete cylinders, which are the cement grades chosen, the CFRP confinement schemes adopted, and the epoxy resin types used.","PeriodicalId":161226,"journal":{"name":"Engineering Research Journal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131325943","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}
