UM students win a best paper award at International Symposium on Thermal-Fluid Engineering
Mr. Jiahang Chen, a doctoral student, and Ms. Kaiwen Wu, a master student, from the Department of Electromechanical Engineering (EME), Faculty of Science and Technology (FST), University of Macau (UM), has won the best paper award at the 4th International Symposium on Thermal-Fluid Dynamics (ISTFD 2023), which was hosted by Nanjing University of Aeronautics and Astronautics (NUAA).
ISTFD is one of the leading annual international forums on Thermal-Fluid Dynamics, which aims to advance scientific knowledge and technology development of Thermal-Fluid Dynamics and relevant emerging, cutting-edge and interdisciplinary subjects. The symposium attracted a total of 156 papers from different universities and state key laboratories from all over the world.
In the symposium, Ms. Kaiwen Wu represented the research group to present a paper titled “Experimental Investigation of Pressure Drop and Heat Transfer Characteristics for Horizontal Flow Using Traditional and 3D-Printed Mini Tubes”. The research project was supervised by Prof. Lam Mou Tam, Professor of Department of EME, and was jointly sponsored by the Science and Technology Development Fund of Macau, the National Natural Science Foundation of China, and the Institute for the Development and Quality, Macau. As an advanced manufacturing technology, Selective Laser Melting (SLM) 3D printing technique, which was one of the additive manufacturing methods, could be used to print sophisticated and small-sized heat exchangers with large heat transfer areas so it has attracted high attention in the thermal engineering community in recent years. Due to the difference in the metal surface characteristics between 3D-printed tubes and traditional tubes, the research team experimentally compared the pressure drop and heat transfer characteristics inside a 3D-printed stainless-steel tube and a traditional cold-rolled stainless-steel tube under isothermal and non-isothermal boundary conditions. The results showed that the friction factors and heat transfer of the 3D-printed tube were different from the traditional cold rolled tube in terms of data trend and magnitude, especially in the upper transition and turbulent regions. Therefore, the new correlations in the upper transition and turbulent regions were developed to predict the friction factors and heat transfer coefficients of the 3D-printed tube for the application in the thermal systems. The efforts and achievements of the research team were fully recognized by experts at the symposium.
澳大學生奪國際研討會最佳論文獎
澳門大學科技學院機電工程系博士生陳佳航和碩士生吳凱雯於南京航空航天大學主辦的第四屆熱與流體動力學國際研討會 (ISTFD 2023)奪得最佳論文獎。
熱與流體動力學國際研討會為熱與流體力學領域主要的國際研討會之一,致力於推動熱與流體力學及相關新興、前沿和跨學科的知識和技術發展。是次研討會吸引了來自世界各地不同大學及國家重點實驗室的投稿,最終僅接收156篇論文。
在研討會上,吳凱雯同學代表研究團隊報告了論文題為《傳統及3D打印水平微管內的壓降和傳熱特性之實驗研究》。此研究課題是由機電工程系教授譚立武指導,並由澳門科學技術發展基金、國家自然科學基金及澳門發展與質量研究所共同贊助。增材製造作為一種先進的製造技術,如選擇性雷射熔化(SLM)的3D打印技術,能打印出體積小但傳熱面積大的特殊熱交換器,因此近年引起了熱力工程界高度關注。由於打印的管道和傳統管道在金屬表面特徵上存在差異,因此,研究團隊在等溫和非等溫的邊界條件下,利用實驗方法比較SLM技術的3D打印不銹鋼管和傳統冷軋不銹鋼管壓降和傳熱特性。實驗結果顯示3D打印鋼管與傳統冷軋鋼管摩擦因子與熱傳系數的數據趨勢與幅度是不同的,在湍流時分別更大。因此,研究團隊針對3D打印管道開發了在過渡流及湍流區域上的摩擦因子與熱傳系數的新關聯式,供熱能系統使用。研究團隊的努力和成果獲得專家們的充分肯定。
UM’s interdisciplinary camp attracts outstanding university students from home and abroad
澳大跨學科研學營吸引海內外優秀大學生
The Faculty of Science and Technology (FST) and the Institute of Collaborative Innovation (ICI) of the University of Macau (UM) jointly organised the Summer Camp for Outstanding College Students for the first time. The summer camp attracted applications from over 600 outstanding students representing more than 80 higher education institutions from home and abroad. According to the participating students, the camp provided a platform for interdisciplinary academic exchange and practice, which had a positive impact on and provided inspiration for learning and personal growth.
The applicants are from 40 double first-class universities in mainland China and renowned universities in Singapore, Hong Kong, and other places. Around 70 outstanding university students were selected to join the camp, and they came from top universities in mainland China such as Fudan University, Shanghai Jiao Tong University, Zhejiang University, and Nanjing University.
During the four-day camp, students not only participated in a series of academic talks and departmental activities, but also had the opportunity to have meals with professors in the same discipline. They also visited the residential colleges, the exhibition hall, the UM Wu Yee Sun Library, and the laboratories in the FST and ICI. Through these experiences, the students gained a deeper understanding of UM’s admissions, academic programmes, and scientific research, and explored the university’s international education setup, its whole-person education system underpinned by residential colleges, and its strength in research and innovation. In addition, the students visited a number of world heritage sites in Macao to learn about the development and history of the city.
Liu Yaxuan, a student from the Harbin Institute of Technology, Shenzhen, said that many students in engineering are fascinated by UM’s advanced laboratory equipment, which clearly demonstrates the university’s strong commitment to scientific research. In addition, the professors are friendly and willing to answer students’ questions regarding further studies, and the arrangement of having meals with professors is very innovative. Another participant, Wu Zhishang, a student from Tianjin University, said that UM’s tranquil campus environment is impressive, and that the camp visits showcased cutting-edge research projects in various fields, which gave him a glimpse of UM’s strengths.
UM’s FST and ICI are committed to promoting the development of technological innovation and education in Macao and to actively expanding exchanges and cooperation with higher education institutions from home and abroad. The Summer Camp for Outstanding College Students is an iconic activity demonstrating the university’s ongoing development and exploration in the field of education, as well as an important initiative to give new impetus to higher education in Macao and mainland China.
澳門大學科技學院及協同創新研究院首次合辦“優秀大學生暑期研習營”,吸引海內外80多所高校的600多名優秀大學生報名。有參與學生表示,是次研習營是一個跨學科的學術交流和實踐平台,對於提升學習和成長均有積極的影響和重要的啟發。
