二、课程摘要

This lecture series will introduce the mathematical control and optimization of fluid mixing and transport associated with incompressible flow models, including the Stokes and Navier–Stokes equations. Our lectures will be devoted to mixing and transport driven by pure advection, where molecular diffusion is negligible, leading naturally to the study of semi-dissipative systems, namely systems that are dissipative in some variables but not in others.

Transport and mixing play fundamental roles in many natural phenomena and engineering applications, including atmospheric and oceanic circulation, pollutant dispersion, ventilation, and chemical processing. Central problems include how to enhance mixing, steer transported scalar fields toward desired distributions, and track evolving fluid interfaces. These problems give rise to challenging questions in nonlinear control, non-convex optimization, and non-smooth analysis. We will discuss issues including well-posedness, existence of optimal controls, differentiability of coupled flow-transport systems, the derivation of optimality conditions, as well as numerical implementation.

The series will conclude with recent developments and several open problems in these topics.
