講題：Magnetic convection of paramagnetic fluid
演講摘要：
Paramagnetic fluid (oxygen, air, etc.) has a low and positive magnetic susceptibility, which means it is attracted weakly to a magnet. Additionally, the magnetic force on the fluid depends on the inverse of absolute temperature of the fluid. This suggests the heat transfer by natural convection can be controlled or the magnetic convection can be induced from a static state by applying an external magnetic field. This has a potential to enhance the heat transfer of heat exchanger, to drive the thermofluid under microgravity, etc. Needless to mention, a strong magnetic field, that is, Tesla-order magnetic flux density is preferred to pronounce its effect. Thus, I introduce some experimental and numerical results using electromagnets and superconducting magnet. However, in terms of an economical view (initial cost and running cost), it is better to employ strong permanent magnets instead of electromagnets. In the next section, the feasibility of using permanent magnets is explained. I’ll show you some examples of locally convection enhancement and suppression, magnetic force convection from thermally stratified fluid layer with and without gravity. Finally, I summarize my talk with my recent topic of my study, oscillation of convection induced by permanent magnets.

講題：LBM for Turbulence and Turbulent Heat Transfer in Complex Flows
演講摘要：
This seminar addresses the limitations of conventional lattice Boltzmann methods (LBMs) and introduces alternative, reliable LBM schemes for turbulence simulations. These include the D3Q27 multi-relaxation time (MRT) LBM, the regularized D3Q19 thermal LBM, and the imbalance correction (iBC) local mesh refinement methods developed by our group. After showcasing the enhanced simulation accuracy of these schemes, several DNS/LES studies on turbulence and turbulent heat transfer over complex surfaces (rough and/or porous walls) are presented. The results illustrate how turbulence and turbulent heat transfer are influenced by wall roughness and/or permeability through the Kelvin-Helmholtz instability.
