【GAMES Webinar 2023-271期】(模拟专题-Fluid Simulations on Surfaces)
报告题目：Position-Based Surface Tension Flow
Jingrui Xing is currently an undergraduate of the School of Electronics Engineering and Computer Science, Peking University, advised by Prof. Baoquan Chen. His research interests lie in physical simulation in computer graphics. He is particularly interested in simulating natural phenomena like fluids, solids, and elastic bodies and their applications in movies and games.

报告题目：Hydrophobic and Hydrophilic Solid-Fluid Interaction
We propose a novel solid-fluid coupling method to capture the subtle hydrophobic and hydrophilic interactions between liquid, solid, and air at their multi-phase junctions. The key component of our approach is a Lagrangian model that tackles the coupling, evolution, and equilibrium of dynamic contact lines evolving on the interface between surface-tension fluid and deformable objects. This contact-line model captures an ensemble of small-scale geometric and physical processes, including dynamic waterfront tracking, local momentum transfer and force balance, and interfacial tension calculation. On top of this contact-line model, we further developed a mesh-based level set method to evolve the three-phase T-junction on a deformable solid surface. Our dynamic contact-line model, in conjunction with its monolithic coupling system, unifies the simulation of various hydrophobic and hydrophilic solid-fluid-interaction phenomena and enables a broad range of challenging small-scale elastocapillary phenomena that were previously difficult or impractical to solve, such as the elastocapillary origami and self-assembly, dynamic contact angles of drops, capillary adhesion, as well as wetting and splashing on vibrating surfaces.
Jinyuan Liu is currently a PhD student in Computer Science at Dartmouth College, advised by Prof. Bo Zhu. His research interests include physical simulation (rigid, soft, cloth, hair, liquid, gas and their interactions), and numerical optimization applied to topology, shape and interfacial physics.
