Course content
|
1. Hydrostatics - equilibrium of liquids, Pascal's law, absolute and relative equilibrium of liquids. 2. Euler's equation of hydrostatics, application of the equation of hydrostatics, Archimedes' law, surface tension, capillary phenomena, resultant force and its area of action on a plane inclined wall. 3. Pressure forces on curved walls, basic state properties. 4. Relative equilibrium of liquids - rectilinear, uniformly accelerated movement in a straight direction, rotation around a vertical axis. Properties of fluids - temperature, density, enthalpy, internal energy, entropy, compressibility, expansivity, vapor tension. 5. Hydrodynamics of inviscid fluids - Lagrange and Euler's method, continuity equation, Euler's hydrodynamic equation, momentum theorem, energy and Bernoulli's equation. 6. Examples of the use of continuity equation and Bernoulli's equation, Pittot, Prandtl and Venturi tubes. 7. Outflow from containers through a connected tube, outflow through a large opening, unsteady flow. 8. Dynamic effects of a fluid stream - the force effect of a fluid stream on a standing and moving plate and on a pipe section. 9. Hydrodynamics of viscous fluids - viscosity, Newtonian and non-Newtonian fluids, laminar and turbulent flow, Navier-Stokes equation, conventional, thrust and momentum boundary layer thickness. 10. Flow with losses, frictional and local losses, hydraulic calculation of pipelines. 11. Laminar flow - tube of circular cross-section, parallel plates, flow down the wall. Turbulent flow - emergence of turbulence, characteristics of turbulent flow. 12. The flowing around bodies - resistance of bodies, buoyancy. 13. Compressible fluid flow - speed of sound, compressibility, Mach number. Standing and moving sound source. Difference between supersonic and subsonic flow. Continuity equation, motion and energy. Law of entropy. 14. Isoentropic flow through nozzles - development of flow in nozzles, critical pressure ratio and quantities in the critical cross-section. Basic nozzle design.
