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.
