In this module the fundamental concepts of hydrodynamics are introduced. The main focus is on inviscid, incompressible flow, but viscous effects including boundary layers and separated flow are introduced as well. The lectures are complemented by laboratory sessions with relevance to the taught material.
This module is double coded with SESA2022 and shares the same lectures and labs.
