Course content

The course contains energy and energy conversion within multi-domain energy systems, consisting of: - Mechanical power transmission (rotary and linear motion). - Hydraulic and pneumatic power transmission (power hydraulics). - Electric power transmission (direct current and alternating current).

The course deals primarily with various forms of energy and their relationships; potential and kinetic energy, as well as the transformation of these forms of energy. Systems engineering principles: multi-domain systems., interface and interaction.

Modeling and simulation of dynamic systems. Mechanical energy and power transmission both linear and rotating, as well as transmission to hydraulic and electrical energy and energy storage in various forms.

The hydraulic power part also deals with basic understanding: hydrostatics, hydrodynamics, impulse rate, losses in pipe systems, valves / components.

The course also deals with basic principles for control of energy transfer: including instrumentation techniques, control strategies and controllers.
