ABSTRACT
Contact line problems have significant implications in various industrial applications. When two or more fluids or solids come into contact, surface effects can lead to complex morphological deformations. Additionally, fluid-solid interactions often necessitate multi-scale analysis. In the face of these challenges, computational fluid dynamics (CFD) plays a crucial role in both mathematical modeling and experimental analysis. In this seminar, I will present several numerical strategies for addressing contact line problems. I will demonstrate the application of a straightforward explicit precondition-correction finite difference method using the free AMR software, Basilisk. Furthermore, I will introduce a more advanced model, the three-phase VOF, in which I propose a hybrid continuum surface tension force to account for surface effects.
I am a postdoctoral research associate working on computational fluid dynamics in Professor Taehun Lee’s group at the City College of New York. I obtained my Ph.D. in Mechanical Engineering from the City College of New York, where I focused on multiphase flow modeling and simulation using the Lattice Boltzmann Method (LBM).
I worked as an intern with researchers in Argonne National Laboratory, where I concentrated on large-scale simulation, distributed systems, and GPU acceleration. Following that, I spent a year as a postdoctoral research associate in Paris, collaborating with Professor Stephane Zaleski on Adaptive Mesh Refinement for multiphase flow. I developed a C++ version of IMEXLBM and conducted scaling work on the Theta and Polaris clusters. Currently, I am developing continuous/discontinuous Galerkin lattice Boltzmann methods based on Nek5000 and NekRS. I am proficient in Python, Fortran, C, and C++, and have expertise in parallel programming libraries such as OpenMP, Kokkos (CUDA), DPC++, and MPI.
