一、主讲人介绍:Jung-II Choi教授
Jung-II Choi, 本硕博均毕业于韩国科学技术院,现为韩国延世大学数学与计算学院教授,博士生导师。主要从事多物理场模拟与计算以及数据驱动建模等方面的研究。在Journal of Computational Physics, Journal of Fluid Mechanics , Building and Environment, International Journal of Heat and Mass Transfer等国际顶尖和权威期刊发表论文90余篇。 二、讲座信息 This talk introduces numerical methods for solving natural convection problems with temperature-dependent fluid properties. The first method is the monolithic projection method with staggered time discretization (MPM-STD), which has been shown to accurately predict 2D and 3D Rayleigh-Benard convection under different thermal boundary conditions. Later, we extend the MPM-STD to the monolithic immersed boundary projection method (MIBPM) with staggered time discretization, which has been shown to accurately impose no-slip conditions and exhibit good stability for 2D and 3D forced and natural convection problems. Finally, we released PaScaL_TCS, an efficient and scalable solver for large-scale direct numerical simulations of natural convective flow considering temperature-dependent fluid properties. The solver has been shown to exhibit good strong and weak scalability up to 131,072 cores and has been verified by conducting large-scale differentially heated vertical convection flow simulations under the Oberbeck-Boussinesq approximation. 时间:2023年4月20日13:00-14:00 腾讯会议:943-333-852 欢迎大家积极参加! 中国海洋大学国际合作与交流处 数学科学学院 |
