报告题目1:IB-LBM Based Numerical Simulations for Heat Transfer and Motion Characteristics of Particles in Multi-phase Flow with Multi-physical Fields

报告地点:威廉希尔学术报告厅
报告摘要:Particulate-fluid interaction systems are ubiquitous in various industrial processes whereas present complex momentum or heat transfer characteristics. Most of the particles in these processes are non-spherical particles (such as, ellipsoid-shaped, cylinder-shaped, tablet-shaped, etc), non-spherical particulate-fluid interaction systems have its own characteristics and difficulties, which differ markedly from spherical particles. The unique geometry of non-spherical particles introduces more uncertainties than spherical particles in particle-particle or particle-fluid interactions for flow structure and mechanism, therefore, the multi-scale structure is more complex than the case of spherical particles in the multi-phase flow and heat transfer process, and there are still many problems worthy of further study. In this work, firstly, a 3D IB-LBM parallel numerical simulation platform for hot stationary particle-fluid coupling system is established, which is based on CPU-GPU heterogeneous computers. Secondly, the LBM-IBM-DEM numerical simulation platform for dynamic evolution process of dense fluid-particle system is established, and then the magnetic particles-fluid phase coupling in two-phase fluid modelling is carried out.
报告题目2:Geometric Flows and Some Related Problems

报告地点:威廉希尔学术报告厅
报告摘要:In this thesis, we focus on the geometric analytic properties of several important geometric flows, including monotonicity of eigenvalues of geometric operators along the Ricci-Bourguignon flow, upper bounds or lower bounds on the first eigenvalue for the Finsler p-Laplacian operator and mean Finsler-Laplacian, Harnack estimates of a nonlinear heat equation for the Finsler-Laplacian and geometric properties of the mean curvature flow in Minkowski Spaces, etc.
