报告题目：Complex Fluids and Soft Materials: A Numerical Perspective（复杂流体和软体的计算方法）
In this talk, I will present my recent work on the development of computational tools for investigating complex physical systems, in particular, fluid and soft body systems exhibiting intricate geometry, topology, and dynamics. This encompasses research areas from computer graphics to computational physics to additive manufacturing and soft robotics, with applications including complex interfacial fluids, virtual human hearts, and microstructural soft robotic grippers, to name a few. I explored these problems from the perspective of computation. A series of new data structures, geometric algorithms, numerical PDE solvers, and optimization techniques that are instrumental in boosting the efficacy of these large-scale computational systems will be presented. In particular, I will try to discuss some of my previous efforts in tackling the computational challenges by investigating and representing the hidden geometry and topology behind physics problems.
The talk consists of two parts: numerical simulation of complex fluids and topology optimization for functional soft materials, corresponding to my Ph.D. dissertation and my postdoctoral research respectively. First, I will present a set of computational infrastructures for the efficient simulation of complex fluids. The applications include surface tension flow, viscous flow, and reacting flow, with a broad class of phenomena including burning flames, droplet waves, water bell, bursting bubbles and paint splashes. Second, I will introduce a computational framework to enable engineers precisely control the mechanical functions of a 3D printed soft machine by pre-programming the material layout of its plethora of printing voxels. A set of prototypical soft robotic designs, such as a compliant robotic gripper and a soft swimming ray, will be demonstrated to showcase the efficacy of the system.
