Research Field
Aiming at the construction of Major National Science and Technology Infrastructure Projects and in order to satisfy the development needs of power and energy equipment models, Digital Twin Research Center focuses on the full life cycle management of design, experiment, processing and manufacturing, operation and maintenance, etc. Main research efforts are devoted to the basic theory, key technology and engineering application of highprecision simulation and test, digital twin modeling, intelligent engine, etc.
Research directions:
1. High-precision simulation and test: grid generation method, high-order numerical method, large eddy simulation, numerical zooming technology of aero-engine, fine measurement and visualization of the unsteady flow field.
2. Digital twin technology of gas turbine engine: artificial intelligence algorithm, digital-twin modeling method, design, virtual experiment and intelligent maintenance based on digital twin for aero-engine and gas turbine.
3. Intelligent engine: online intelligent prediction and self-correcting of aeroengine and gas turbine performance, intelligent perception and prediction of instability, adaptive flow control.
Team Building
The center currently has 10 research staff and 19 postgraduate students.
Project and Major Achievement
The center members are leading and participating projects from the National Natural Science Foundation of China, basic scientific research from National Major Project of Aero Engine & Gas Turbine and Science Center for Gas Turbine, Major Research and Development of Ministry of Science and Technology of China, Foundation from Central Military Commission of Science and Technology, International Partnership Program of Chinese Academy of Sciences, etc.
In 2023, the center focused on the construction goal of digital twin for aeroengine and gas turbine, and developed methods of high-precision simulation and test, digital-twin modeling and virtual-real interaction experiment for main components of Major National Science and Technology Infrastructure, and fast performance prediction and agile design for turbomachinery. Also, a novel concept of amphibious aerospace power was proposed.
