This course builds on the foundations of fluid dynamics to describe hydrodynamic flows and provides an introduction to cavitation.
Learning objective
The main learning objectives of this course are: 1. Identify and describe dominant effects in liquid fluid flows through physical modelling. 2. Identify hydrodynamic instabilities and discuss the stability region 3. Describe fragmentation of liquids 4. Explain tension, nucleation and phase-change in liquids. 5. Describe hydrodynamic cavitation and its consequences in physical terms. 6. Recognise experimental techniques and industrial and medical applications for cavitation.
Content
The course gives an overview on the following topics: hydrostatics, capillarity, hydrodynamic instabilities, fragmentation. Tension in liquids, phase change. Cavitation: single bubbles (nucleation, dynamics, collapse), cavitating flows (attached, cloud, vortex cavitation). Industrial applications and measurement techniques.

Performance assessment
Performance assessment information (valid until the course unit is held again)
The performance assessment is only offered in the session after the course unit. Repetition only possible after re-enrolling.
Mode of examination
written 120 minutes
Additional information on mode of examination
The written final exam (taking place during the examination session) covers all contents of this course, including lectures, exercises as well as numerical and experimental assignments. It counts 60% towards the final grade. Additionally, there will be a compulsory continuous performance assessment (counting 40% towards the final grade) divided in three parts: (i) 10% will be based on numerical exercises (e.g., solving hydrodynamic ODEs using Matlab), (ii) 20% will rely on a lab report based on an experiment performed in groups of 5 students and (iii) the last 10% will be based on a 10-min presentation (group of 3-4 students) on a case study of cavitation.
Written aids
One page (A4, two-sided) of own handwritten notes on the subject.
This information can be updated until the beginning of the semester; information on the examination timetable is binding.
