Hydrodynamics and elasticity 1100-4HaE

The course will cover a range of topics, such as:

1. Continuum description of matter, conservation laws and fundamental equations - Navier-Stokes and friends;
2. Hydrostatics: pressure, lift force, stability, ships and balloons
3. Inviscid flows: Euler equations, potential flows, lift force, d'Alembert paradox
4. Viscous flows: Why do planes fly? Boundary layer and explanation of aerodynamic lift. Low-Reynolds numbers and the Aristotelian world. Swimming of microorganisms;
5. Flows with a twist: Vortices – bathtub vortex versus tornado.
6. Elasticity theory: Stress and deformation, bending and twisting of shafts rods, microtubules, and DNA.
7. Waves: Shallow- and deep-water, capillary waves and tsunamis; seismic waves.
