Knowledge
The good student will be able to understand and deal with the fundamental laws of fluid dynamics and will be able to understand and implement dynamic models of unusual continuous media, such as charged, non mass conserving, laser irradiated, multispecies and granular flows.
He will also be able to link macroscopic transport properties and microscopic characteristics of fluid.
Assessment criteria of knowledge
During the oral exam the student has to demonstrate a good comprehension of the fundamental theoretical contents of fluid theory and the link with the microscopic properties of the flowing matter. It is also required that he is able to face properly a real world example of fluid motion, find and discuss an appropriate model to treat and possibly to solve it. No complex mathematical elaboration will be required, but a clear understanding of the mathematical background.
