Hydrodynamics and Elasticity

Rok akademicki: 2024/2025
Semestr: zimowy

OPIS PRZEDMIOTU

The theoretical framework known as hydrodynamics and elasticity provides a powerful and complete description of our world at macroscopic scales (i.e., at large spatial and time scales compared to the molecular ones). The macroscopic dynamics of a variety of complex systems, such as biological and soft materials, atmospheric clouds, and the crust of the Earth, poses a formidable challenge for theoretical modeling, in which knowledge of classical hydrodynamics and elasticity is a major prerequisite. This course gives an introduction to the derivation of the basic equations of hydrodynamics and elasticity as well as common methods for their solutions in simple applications.

We will meet weekly according to the schedule published in USOS.

  • Lecture: Tuesdays, 13:15 - 16:00 (Gustavo Abade)
  • Tutorials: Thursdays, 9:15 - 12:00 (Marta Wacławczyk)

Program:

  1. The fundamental equations of continuum mechanics;
  2. Inviscid flows: Euler equation, sound waves, potential flow, lift and drag forces exerted by moving fluid on immersed bodies;
  3. Viscous flows: Navier-Stokes equations, boundary layer and explanation of aerodynamic lift. Micro-hydrodynamics and swimming motion of flagellated microorganisms;
  4. Waves: shallow- and deep-water, capillary waves;
  5. Elasticity theory: Stress and deformation, bending and twisting of shafts rods.

Assessment:

The final assessment will be based on one test (kolokwium) and a written exam. A tentative schedule for examinations is:

  • Test: Thu 5 December 2024 (9:15 - 12:00)
  • Exam: Thu 23 January 2025 (9:15 - 12:00)
