Graduate Xu Xiaomeng: Published a top paper, "GAP" has made a new realm

The busy and busy summer vacation comes to an end, and the students are widely welcomed by the students. Xu Xiaomeng, a 2017 graduate of chemical engineering in Guangdong Israel Institute of Technology, continued to stay in school as a scientific research assistant after graduation. Recently, one of the three classic journals recognized by the first author in the international chemical industry, "Indostric & Engineering Chemistic Research" paper. At the same time, she has gained a graduate OFFER of chemical and biotechnology, German Munich University of Technology in the undergraduate research.

"Industrial & Engineering Chemistry Research" is the top journal of the American Chemistry Society (ACS). It aims to publish the latest high -quality original research in the global chemical engineering application field. The thesis entitled "Research on the Flowing Behavior of Flowing Dynamic Coupling Models to Calculate the Fluid Dynamics Coupling Model" (Coarse-Grained DEM-CFD SIMULATION OF FLUIDIRAOR of Irregular Shape Sand PARTICLES "), Gao Xi, an associate professor of chemical engineering, is the author of the article communications, and Li Cheng, an associate professor of mechanical engineering, is the second author.

Due to the complexity and time -consuming of granular shapes and simulation (high costs), precise modeling and simulation of the fondization of irregular shape sand particles are challenging. The study uses a rough-grained discrete element (CG-DEM) -Cousting the fluid dynamics (CFD) coupling model, that is, by modifying a certain amount of physical particles into a virtual particles to improve the calculation feasibility of traditional CFD-DEM.

"Before the laboratory to the factory production and industrialization promotion from laboratory to the factory production and realization of industrialization, it is a vital step to build a model." Xiaomeng introduced, "Our work is based on the results of the laboratory and by building the construction of the laboratory. Relatively accurate simulation reactors, reduce the time and cost loss of simulation, and prepare for the successful production in the future. How to design the pipeline size of the pipeline? Do you need to consider the friction loss of the content in the pipe? These are all issues that need to be considered. "

In the research, the research group amended the CGDEM-CFD model, introduced the rolling friction model, simulated the flowing behavior of irregular shaped sand particles in the fluidized bed, and evaluated several key model settings to identify key model factors. At the same time, by comparing the simulation results with the experimental data, the paper quantifies the effects of model parameters on fluid dynamics. The results show that the application of rolling friction models can improve the simulation accuracy of non -spherical sand -grained behavior. The model established in the paper accelerates the simulation efficiency under the premise of ensuring certain simulation accuracy.

Due to his interest in the field of simulation computing, Xiao Meng joined Professor Gao Xi's research group at the undergraduate stage and participated in the multi -scale modeling and application research of the multi -phase current reactor of the chemical industry. After graduating in 2021, Xu Xiaomeng did not go directly abroad as most of his classmates, but decided to take the initiative to start the life of "GAP Year" (interval): as a research assistant of the research group, staying in Guang to continue to carry out scientific research work, and at the same time Do not give up the pursuit of German colleges and universities that you like, and strive to improve yourself. He hopes to go to Europe to study with a better mental appearance and higher scientific literacy.

This sunny girl admits that it takes courage to take a step of "Gap Year" in the contemporary fast -paced competition, but this year also made her gain a lot. This summer, while publishing papers in top journals, Xu Xiaomeng also wished graduate offers from chemical and biotechnology at the University of Munich University of Technology as expected to interpret "Gap Year" a new state of choice and gain.

Munich University of Technology was founded in 1868. It is the world's top university with international reputation. So far, 17 Nobel Prize winners have been trained. In the ranking of various international universities, it ranks first in Germany for many years and is one of the German TU9 League University.

The instructor Gao Xi praised Xu Xiaomeng's outstanding performance:

"Xiao Meng has a strong spirit of research. Not only does it have a deep understanding of the research direction through a lot of reading, but also a large number of fluid mechanics computing has also been made. The valuable thing is that she can work unremittingly in her goals. In daily life, she also has a strong organizational ability. The activities of the research group are responsible for organizing arrangements, and everything is conducted in an orderly manner. "

Xu Xiaomeng spoke at the academic conference

As an excellent graduate of the "wide -to -one period", Xiao Meng grew up with his alma mater and transformed into a new young man with innovative ability, global vision and humanistic literacy. She believes that although the teaching environment of the whole Britain is a challenge, it can make students adapt to the internationalized academic environment as soon as possible. More importantly, Guangyi has given students a broad space for students to explore freely. "I can try different research groups according to my interests, and I can also go to the academic conference of 'big coffee gathered'. Get a lot of exercise. "Looking back on the various achievements of the road of" research ", in addition to the precipitation and accumulation of the college period, Xiao Meng is also grateful to the instructor:" If you have difficulties, find Teacher Gao Xi! Teacher Gao's students in the area of ​​each of the research group often encouraged us to boldly try to guide us to play and try scientific research innovation. "In October, Xiaomeng was about to end the" Gap Year "and set off to study in Germany. "Life is a marathon instead of racing, keeping your own rhythm, and if you want to do something, do it boldly!"
