Topics of seminars according to weeks:
1st week: Introduction, basic fluid properties: compressibility, expansibility, extensibility. Statics of fluids ? fluid pressure, Euler´s static equation, pressure and pressure level equation including potencial formulation, Pascal´s law and its application.
2nd week: Incompressible and compressible liquid in gravitational field, relative balance of liquids in containers under external acceleration.
3rd week: Liquid force acting on plane and curved surface, determination of hydrostatic centre, force acting on floating body - Archimedean principle.
4th week: Floating body stability. Introduction into fluid dynamics, classification of Newton flows according to viscosity, compressibility, stationarity, effective particles and geometric arrangement. Eulerian and Lagrangian flow descriptions.
5th week: Trajectories and streamlines. Momentum and continuity equation for flow tube. Viscous flow ? molecular and molar viscosity.
6th week: Laminar, transition and turbulent flow in a tube, dependence on Reynolds number. Normal and shear stress in fluid, their generalisation into stress tensor.
7th week: Navier-Stokes momentum equation, continuity equation of 3-D flows - mathematical and physical properties.
8th week: Theory of similarity in mechanics of fluids. Derivation of similarity criteria from basic partial differential equations. Production of criteria equations.
9th week: Simplification of the Navier-Stokes equation into Bernoulli one in different forms valid for inviscid and viscous flows, for incompressible and compressible ones. Solution of some examples.
10th week: Total, static and dynamic pressure and pneumatic instruments for their measurement. Liquid outflow through a small orifice into surrounding air, outflow through a short cylindrical adapter ? arising and explanation of cavitation.
11th week: Further outflow cases: submerged orifice, large hole in liquid container, water overflow and imperfect overflow. Outflow time calculation and time determination of liquid level equalisation in connected vessels.
12th week: Linear momentum equation and its technical applications: forces acting on moving blades, power output of radial turbine, function of centrifugal pump or compressor.
13th week: Laminar and turbulent velocity profiles in tubes. Local and friction pressure losses, hydraulic smooth and rough surfaces, Prandtl´s function of roughness.
