Date 2020-08-31 - 2020-12-04

General course objectives

To provide the student with the necessary theoretical background for applying modern scientific methods for analyses of flows with lift, free surface and cavitation, i.e. flows over ships, rudders and propellers. The students will be able carry out hydrodynamic analyses and optimization of propulsion and manoeuvring of ships.


Applications include: Potential flows, flow with free surfaces, dynamic lift, cavitation. Flows over ships that sail on a straight course or do horizontal motions, i.e. wave formation, vortices and friction. The course also contains flows over rudders and propellers including dynamic lift, cavitation and pressure pulses. Manoeuvring simulation. The synthesis of applications addresses ship technical operations, i.e. ship propulsion and manoeuvring.
