Introduction to Hydrodynamics

This lecture introduces the fundamental concepts of hydrodynamics, covering topics such as drag reduction, two-phase flows, geophysics, tidal energy harvesting, fish propulsion analysis, flow classifications, viscous and inviscid flows, instabilities, turbulence, and tools for solving hydrodynamic models. The instructor emphasizes the importance of developing intuition to avoid common engineering pitfalls when using computational fluid dynamics software.
