Abstract: The multiscale heat transfer and fluid flow problems are divided into two categories: multiscale system and multiscale process. Multiscale system is characterized by large variation in length scales in which the processes at different length scales have the same governing equations and can be solved by the same numerical method. The top-to-down solution approach with increasing grid finesses is adopted with the cooling of a PCB as an example. In the multiscale process phenomena at different geometric levels have different governing equations and solved by different numerical methods. For such process information exchange at the interfaces of different governing equations is the key for an efficient and accurate numerical solution. The transmission of solutions from mesoscale (microscale) to macroscale (mesoscale) is easy to be implemented, while the reverse, transmission of less information to more information (reconstruction) is a challenging issue in the multiscale simulation. Several reconstruction operators developed in the speaker’s group are presented and their application examples are presented.
Prof Wenquan Tao pursued his undergraduate and graduate studies in Power Machinery Engineering at Xi'an Jiaotong University. He has then joined the faculty of the University since 1966. He was a Visiting Scholar at the Heat Transfer Laboratory of the University of Minnesota, Guest Professor at Kyushu University, and Visiting Professor at The Hong Kong Polytechnic University. He is currently President of Xi'an Jiaotong-Liverpool University, and Professor of Energy and Power Engineering at Xi'an Jiaotong University. He is also an Adjunct Professor at Tongji University and HKUST.
Prof Tao’s research interests focus on heat transfer and fluid flow problems, including advanced numerical methods for simulation of fluid flow and heat transfer and their applications, multiscale simulation of heat transfer and fluid flow problems, and cooling techniques for electronic devices and equipment.
Prof Tao received numerous awards for his achievements in both research and teaching, including the National Science and Technology Awards, National Natural Science Award, China Universities Science and Technology Award, Technology Progress Award of the Ministry of Electric Power Industry, and Special National Teaching Achievement Award, etc. In 2003, Prof Tao was awarded the National Distinguished Professor honored by the Ministry of Education. In 2005, he was elected Member of the Chinese Academy of Sciences. In 2006, he won National May 1st Labour Medal. Prof Tao is an associate chief editor of two international journals dealing with papers submitted by Chinese authors, and a member of editing board of three international journals. Currently, Prof Tao is Vice Chairman of the Heat Transfer Committee of the Chinese Association of Engineering Thermophysics. He has published 110 papers in various international journals, and over 60 international conference papers; and he has also published over 170 papers in various Chinese journals, and written 10 books and textbooks. He owns 6 invention patents.
