Systems with many particles or continuous systems are of eminent importance in science and engineering. Such systems are considered from the viewpoint of fluid dynamics, thermodynamics and wave propagation. Having a unified treatment in mind, wave phenomena are considered also for electromagnetic waves.

The focus is towards the main concepts underlying the considered physical theories. Based on this basic understanding first practical problems are analyzed mathematical.

The contents of the course are accompanied by practical lab experiments.

Fluid dynamics:

1. Fundamentals (material quantities and physical properties of fluids, hydrostatics)
2. Kinematics of fluids (continuity equation)
3. Fluid kinetics (Bernoulli's equation, conservation of mass, (angular) momentum theorem)
4. Laminar and turbulent flows, Reynolds number

Thermodynamics:

1. Fundamentals (thermodynamic system, system boundaries, thermal state variables, thermal equations of state, ideal gases)
2. Energy balances, first law of thermodynamics, internal energy, heat, work done on volume change
3. State changes of ideal gases, isotherms, isobars, isochores, isentropes
4. Energy conversions, second law of thermodynamics, entropy, reversible and irreversible state changes
5. Thermodynamic cycles, thermal efficiency, Carnot cycle, ideal comparison processes, heat pump
6. Heat transfer: heat conduction, convection

Waves:

1. Preliminary remarks on oscillations
2. Wave equation, reflection, interference, refraction, diffraction

The total workload for the module is 150 hours (see also "ECTS credit points and grading").
