主 题： 气动热多尺度数值仿真
高压涡轮内的流动有着宽广的时间和空间尺度，比如缓慢的热传导和快速的流体对流，通道内的大尺度宏观流动和气膜冷却的小尺度流动。在传热和冷却高保真数值仿真中，这些不同的时空尺度都需要得到解析。本次讲座将介绍高压涡轮气动热多尺度数值仿真的进展。
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.
