Title: Applications of an immersed boundary-lattice Boltzmann method for the fluid-structure interactions in blood flow and insect flight
Abstract: The fluid-structure interaction (FSI) problems are common in nature, particularly in engineering and biological applications. Nevertheless, a comprehensive study of such problems remains a challenge due to their strong nonlinearity and multidisciplinary nature. The immersed boundary method has attracted growing interest in the computational fluid dynamics research community due to its simplicity in dealing with moving boundaries. The lattice Boltzmann method is an alternative and promising numerical scheme for fluid flow simulations due to its advantages of simplicity, explicit calculation, and intrinsic parallel nature. An immersed boundary-lattice Boltzmann method for the FSI will be presented, demonstrated by successful blood flow and insect flight applications.
Presenter: Mr Qiuxiang Huang is working on multi-disciplinary research that crosses between engineering and biology. He is interested in developing multi-scale coupling techniques for scientific and high-performance computing, including fluid-structure interactions with applications in blood flow, insect flight and low-Reynolds turbulence. He worked on developing fluid-structure interaction solvers for simulating collapsible blood vessels during his PhD at Flow Science Lab at the University of New South Wales Canberra (UNSW Canberra). He continued his research career at UNSW Canberra as a Research Associate, working on understanding insect flight based on the combination of computational and experimental techniques.
