Abstract:

Microscale acousto fluidics is the physics of ultrasound propagating in and interacting with fluids, solutions, and particle suspensions on the sub-millimeter scale.In the lecture, he will summarize some of the recent results within continuum theoryand numerical simulation of microscale acousto fluidic systems that he haveobtained in collaboration with his students and international colleagues. The main emphasis will be on three dynamical ultrasound effects: The acousticradiation force acting on suspended micro- and nanoparticles including thermoviscous effects, the acoustic streaming appearing in the fluid, and the newly discovered acoustic body force acting on inhomo geneous solutions. 

Short biography:

Henrik Bruus received his PhD degree in physics from the Niels Bohr Institute, University ofCopenhagen in 1990, and then worked as postdoc at Nordic Institute ofTheoretical Physics 1990-92, Yale University 1992-94 and CNRS Grenoble 1994-96.He returned to the Niels Bohr Institute as associate professor 1997-2001,before moving to the Technical University of Denmark in 2001. There, he becamefull professor of lab-on-a-chip systems in 2005 and of theoretical physics in2012. His current research interests comprise micro/nano fluidics,acoustofluidics, electrokinetics, the physics of on-chip cell manipulation, themotion of sugar in living plants, and topology-optimized microflows. He has(co)authored 140 journal papers (including Rev. Mod. Phys., Nature Comm., PRL,PRE., PRApplied, Lab on Chip) on condensed matter physics and microfluidics,200 conference papers, and 2 monographs, the latest being Theoretical Microfluidics, Oxford University Press (2008). He has more than 4000journal paper citations and the H-index is 38.  


报告简介:

微尺度声速学是超声在亚毫米尺度上传播和与流体、溶液和颗粒悬浮液相互作用的物理。在此次报告中,Henrik Bruus教授将总结一些他与国际同事、学生合作中获得的连续理论和数值模拟中的最近的结果。重点将放在三种动态超声效应 :(1)在悬浮微纳米粒子上的声辐射力和纳米粒子包括热传导效应;(2)在流体中出现的声流;(3) 在非齐次溶液中发现的声波体力。

报告人简介:

Henrik Bruus教授于1990年从哥本哈根大学的尼尔斯·玻尔研究所获得物理学博士学位。随后,1990- 1992年在北欧理论物理研究所、1992-1994年在耶鲁大学、1994-1996年在格勒诺布尔大学从事博士后研究。1997-2001年,他以副教授的身份回到了尼尔斯玻尔研究所,之后,在2001年进入丹麦科技大学。在那里,他在2005年成为了实验室芯片系统的教授,以及在2012年成为理论物理学教授。他目前的研究兴趣包括微/纳米流体、声光学、电动力学、芯片细胞操纵的物理学、活植物中的糖的作用以及拓扑优化的微流。他写了140篇期刊论文,200篇会议论文,2篇专题论文。他有超过4000份的论文引用,而h指数是38。
