However, the installation of utility networks has often been lacking in coordination, resulting in frequent disassembly and reinstallation. Given these circumstances, the objective of this research is to provide valuable insights and ideas to the government regarding the model of Integrated Utility Network Facilities, along with effective implementation methods and accurate construction cost estimation. This will be done while considering the presence of existing facilities and infrastructure. The research employed a quantitative descriptive method, utilizing a case study approach focusing on several roads in the city center as a pilot project. The objective of implementing integrated utility networks and infrastructure (ducting utilities) in Denpasar City is to establish coordination among agencies responsible for underground network utilities. The goals include maintaining a neat, orderly, and clean city environment, facilitating easier and more cost-effective network maintenance, avoiding damage or interference caused by third-party works, enabling information sharing in the event of network damages, and promoting environmental friendliness.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116436397","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}

Despite the many benefits that can be derived from microgrids, they still face many barriers to participating in the electricity industry compared to traditional grids. This paper proposes to address the implications of installing renewable energy in the parish 5 de Agosto, Stone Mine Sector of the city of Esmeraldas, through a technical-economic analysis of the implementation of a microgrid using the HOMER network software. The analysis shows that implementing a microgrid for renewable energy production significantly reduces total costs, unit energy costs and carbon dioxide emissions over the entire project life cycle. Finally, it is concluded that the photovoltaic matrix produces 82.3%, wind turbines 15.3% and the contribution from the grid is 2.45% of the total energy, respectively. The percentage of renewable energies in the system is 100%.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115032772","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 silicon flow is in the annular gap between two concentric cylinders as the internal cylinder is rotating while the outer cylinder is stationary. Taylor vortices are formed between the cylinders and the rotational Reynolds number also varies from 700 to 4500. The carrier flow is silicone while air bubbles are constantly injected into the carrier phase at the bottom of cylinders and rise through the flow. By employing a discrete phase model and Euler-Lagrange approach, we investigate a two-phase turbulent flow. In this way, we study the distribution of the bubbles through the flow, which is acquired using numerical modeling. Our numerical results are in good agreement with the experimentally reported data for different values of Reynolds numbers. We also investigate the effect of injected air with a constant flow rate on the skin friction drag and on the drag coefficient ratio. Our numerical results illustrate a reduction of drag about 36% when microbubbles are injected into the system. This reduction can be achieved by the effect of the bubbles on the density of the fluid and transformed momentum.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129904056","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}
