报告题目Thermal Stratification in Geophysical Fluid Flows

报告人姓名: 赵昆  杜兰大学副教授

报告时间: 2020.1.06(星期一)上午10点

报告地点: 数统院307


报告摘要The two-dimensional incompressible Boussinesq equations have been routinely used to model systems across atremendous range of length and time scales frommicrofluidics and biophysics to geodynamics and astrophysics. It plays an important role in the study of atmospheric and oceanographic turbulence as well as other situations where rotation and stratification play a dominant role. In addition to its own physical background, the model is also known for its close connection with fundamental models in mathematical fluid mechanics, such as the incompressible Euler and Navier-Stokes equations. In a special situation, the vortex formulation of this two-dimensional model in Eulerian coordinates is formally identical to the vortex formulation of the three-dimensional Euler equations in cylindrical coordinates for axisymmetric swirling fluid flows, which makes it a tremendously rich area for mathematical investigations. The theme of this talk is oriented around the rigorous mathematical demonstration of one of the common phenomena in geophysical fluid flows:  thermal (vertical) stratification. In addition, some recent results on the stability of dynamic shear flow will be reported. Moreover, some open problems and numerical experiments will be discussed.
