Topics of lectures by weeks 1 Basic properties of fluids: compressibility, expansibility, extensibility; surface tension, viscosity ? examples. 2 Sound velocity in gases and liquids. Statics of fluids, Euler´s static equation, Pascal´s law and its application. 3 Relative balance of fluids: liquid in gravitational field, rectilinear accelerated movement of vessel, rotational movement round vertical and horizontal axis - examples. 4 Fluid forces acting on plane and curved surfaces including determination of hydrostatic centre ? examples. 5 Stability of floating bodies ? example. Introduction to fluid dynamics, criterions for simplification of flows, Euler´s and Lagrange´s description, basic notions (stream- and vortex filament etc.). 6 Continuity and movement equations for stream tube. Kinematics of fluids: solution of velocities and pressures in unviscid fluid. 7 Simple potential flows and their compositions ? examples. 8 Viscous flows: tension in flowing fluid, movement equation Navier-Stokes, direct solution of simple cases by help of N-S equation. 9 Simplification of N-S equation to Bernoulli equation, technical applications for uncompressible and compressible flow. 10 Similarity in fluid mechanics, similarity criterions and their physical meaning, criterion equations. 11 Total, static, dynamic pressure and their meassurement. Linear momentum equation with examples of using. 12 Laminar and turbulent velocity profiles in channels of different cross section shape. Liquid outflow from a vessel and calculation of outflow time. Examples. 13 Formation of cavitation. Recognition of hydraulic smooth and rough surfaces. Local and friction pressure losses in tubes ? examples. Topics of seminars by weeks. 1 Compressibility, expansibility, extensibility; surface tension, capilar elevation and depression ? examples. 2 Velocity of sound in gases and liquids solved by calculation. Laboratory training: measurement by pneumatic probes. 3 Examples dealing with pressure and pressure level distribution in vessels at different kinds of movement. 4 Calculations of hydrostatic forces (including centres) acting on plane and curved surfaces. Laboratory training: measurement of velocities and turbulences by hot wire anemometer. 5 More complex calculation of liquid forces acting on curved surfaces needing grafical analysis.

Laboratory training: Demonstration of flow visual representation and velocity measurement by Particle Image Velocimetry method. 7 Analytical solution of simple examples of potential flow: velocities, streamlines, pressures. 8 Solution of simple problems by using Navier-Stokes equation. Laboratory training: Measurement of the nuclear reactor fuel element model from the streaming point of view. 9 Calculation of invisced tasks by using general and algebraic Bernoulli equations together with contiunity equation. 10 Problems connected with similarity in fluid mechanics. Illustration of making criterion equation. Laboratory training: Acquainting the students with 2 stends for the flow induced vibrations in fluid coupled systems ? measurement demonstration.. 11 Examples oriented on linear momentum equation and its using for blade turbomachines, their output or input. 12 Calculations of velocity profiles of laminar and turbulent flow in various channels (for instance in wedge-shaped gap of segment bearing). Laboratory training: Measurement on water turbin model. 13 Calculations of local and friction pressure losses in tubes and tube networks.
