主 題： 氣動(dòng)熱多尺度數(shù)值仿真
高壓渦輪內(nèi)的流動(dòng)有著寬廣的時(shí)間和空間尺度，比如緩慢的熱傳導(dǎo)和快速的流體對流，通道內(nèi)的大尺度宏觀流動(dòng)和氣膜冷卻的小尺度流動(dòng)。在傳熱和冷卻高保真數(shù)值仿真中，這些不同的時(shí)空尺度都需要得到解析。本次講座將介紹高壓渦輪氣動(dòng)熱多尺度數(shù)值仿真的進(jìn)展。
Topic: Multi-scale Aerothermal Modelling
The flow within high pressure turbines has rich time scales and length scales. For example, slow solid conduction vs fast fluid convection, macro passage flow vs micro film cooling flow, etc. To resolve all those scales as required by heat transfer and cooling analyses are very challenging. This lecture presents some recent effort and progress using a multi-scale approach.
Speaker’s Biography
Prof. Li He is the Chair Professor of Computational Aerothermal Engineering at the department of Engineering Science of Oxford University. He is also the Oxford Co-director of the Centre for Doctoral Training (CDT) in Gas Turbine Aerodynamics, jointly established with Cambridge and Loughborough universities. Prof. Li He was the head of Osney Lab (2008-2011) and the acting director of Rolls-Royce University Technology Center in Heat Transfer and Aerodynamics (2008-2010).
His main research interest has been in Computational Fluid Dynamics with emphasis on unsteady aerodynamic/aero-elastic and heat transfer phenomena in turbomachinery. He has directed research projects in unsteady flows and aeroelasticity and consulted for several major gas turbine/aeroengine and steam turbine companies in Europe, US and Asia.
He has been a review organiser and committee member for several international conferences. External editorial services include:
- Guest Editor, International Journal of CFD (special issue on Fourier methods);
- Associate Editor, ASME Journal of Turbomachinery;
- Associate Editor, the Aeronautical Journal.
He is Fellow of American Society of Mechanical Engineers (ASME) and Fellow of Royal Aeronautical Society (RAeS).
