Abstract | This course builds on the foundations of fluid dynamics to describe hydrodynamic flows and provides an introduction to cavitation. | |||||||||||||||||||||||||||||||||||
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.
