This Lecture Course is devoted to the modern mathematical theory of complete fluid systems - the fluid flows satisfying the basic physical principles of conservation of mass, momentum, and energy. Our approach is based on the concept of weak solution introduced in the monograph [M].
The main topics include:
- Basic equations of mathematical fluid dynamics, the Navier-Stokes-Fourier system
- Weak vs. strong formulation, basic properties, advantages, shortcomings
- Nonlinear equations and a priori bounds, global dissipation inequality and related questions
- Relative entropies, weak-strong uniqueness, long-time behavior of complete fluid systems
- The property of (weak) sequential stability
- Principal ideas of the mathematical theory of global-in-time large data solutions, the effective viscous pressure, commutator estimates, div-curl lemma
- More advanced topics related to complete fluid systems, model reduction and singular limits
