Building Information Modeling (BIM) is a highly promising technique for achieving digitalization in the construction industry, widely used in modern construction projects for digitally representing facilities. Nevertheless, retains limitations in terms of representing construction operations. The digital twin concept may potentially overcome these limitations and initiate advanced digital transformation in the construction industry as it has revolutionized the product lifecycle management in the manufacturing industry. This research provides a critical review of applying digital twin in the construction industry. Altogether, 140 papers from related journals and databases were reviewed. The digital aspect of twinning consists of BIM and simulation modeling. These two techniques have been used to create virtual or digital representations of actual buildings and real-world construction processes. However, integrating and applying BIM and simulation modeling according to the digital twin concept remains to be fully studied. Comprehensive evaluations of BIM, simulation modeling, and digital twin will provide a well-defined framework for this research, to identify direction and potential for digital twin in the construction industry, thereby progressing to the next level of digitalization and improvement in construction management practice.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"242 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75322078","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 turbulent flow was analyzed using the Standard k-? model. There are two scenarios in this simulation study. One is to investigate the consequences of having the expressways and their resulting PM2.5�emissions. The other is to examine the influence of the COVID-19 pandemic and the city lockdown which affected the traffic volumes. The presence of the expressways in Din Daeng district was demonstrated to enhance PM2.5�concentrations. The presence of the expressway increased the concentration of PM2.5�by approximately 3.4 times compared to the case of no expressways.�The COVID-19 pandemic seemed to have�an impact on the concentration of PM2.5�during the city lockdown. During the city lockdown,�the concentration of PM2.5�was reduced by approximately 63% compared to the normal period.||ดินแดงเป็นเขตขนาดเล็กและมีประชากรอาศัยอย่างหนาแน่นของกรุงเทพมหานคร�ทำให้ความเข้มข้น PM2.5 ในเขตดินแดงเกินมาตรฐานรายวันและประจำปีของมาตรฐานคุณภาพอากาศ ในงานวิจัยนี้พลศาสตร์ของไหลเชิงคำนวณ (CFD) ถูกนำมาใช้เพื่อตรวจสอบผลกระทบของลักษณะเมืองและปริมาณการจราจรต่อการกระจายตัวของ PM2.5 ในเขตดินแดง โดยใช้แบบจำลอง Standard k-? มีการศึกษาสองสถานการณ์ในงานวิจัยนี้ หนึ่งคือการตรวจสอบอิทธิพลของการมีทางพิเศษและการปล่อย PM2.5 ที่เกิดขึ้น อีกประการหนึ่งคือการตรวจสอบอิทธิพลของการระบาดของโรค COVID-19 ที่ส่งผลกระทบต่อปริมาณการจราจร จากผลการจำลองแสดงให้เห็นถึงการมีอยู่ของทางพิเศษในเขตดินแดงเพิ่มความเข้มข้นของ PM2.5 เมื่อมีทางพิเศษจะเพิ่มความเข้มข้นของ PM2.5 ขึ้นประมาณ 3.4 เท่า เมื่อเทียบกับกรณีไม่มีทางพิเศษ การระบาดของโรค COVID-19 จะส่งผลกระทบต่อความเข้มข้นของ PM2.5 ในระหว่างการล็อคดาวน์นั้น�ความเข้มข้นของ PM2.5 ลดลงประมาณ 63% เมื่อเทียบกับช่วงเวลาปกติ","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"189 4 Suppl 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80088227","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}

Phuphuak, Somchai Kongnoo","doi":"10.4186/ej.2022.26.12.1","DOIUrl":"https://doi.org/10.4186/ej.2022.26.12.1","url":null,"abstract":". The propos is a new design and development of an advanced separator for oil production in Thailand on a prototype scale to order to avoid deposition of sand contaminated include oil production. The novel separator was designed by installing a series of impellers along the horizontal bottom of the separator. The system was successfully implemented on the laboratory scale. A computational fluid dynamics (CFDs) model is employed to investigate the 3D hydrodynamics and flow behavior inside the separator tank modified with impellers. The CFD simulation was operated for 300 min. It could fundamentally demonstrate the flow phenomena of the crude fluids that the sand flowing out from the separator through the water outlet part depends on the accumulation of sand packing bed near the open channel of the outlet and including the effect of impeller rotation. It also shows the wave pattern of the sand outlet and the movement of the impeller did not disturb the efficiency of oil-water phase separation. In the laboratory experiments, the optimum conditions for sand separation in the water outlet part were investigated in terms of impeller sizes, the rotational speed of impellers, and the effect of duration times. The impeller sizes were compared between 3 inches and 5 inches in diameter. The results show that 5 inch-impeller is the optimum size for preventing the sand packing in this system. It was found that 200 rpm gave the most powerful speed of rotation to remove sand to the open channel. From all over the results of the CFD simulation and lab experiment, it could be concluded that the separator system with a strong rotation of impellers leads to effectively prevent sand sedimentation in the separator.","PeriodicalId":32885,"journal":{"name":"AlKhawarizmi Engineering Journal","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81419330","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}
