Course content
LES with dynamic Smagorinsky model and flow separation, wave analysis of a fixed or floating vertical cylinder by nonlinear potential theory in long wave regime, Morison's equation, wind turbine and wake aerodynamics, blade-element/momentum theory, rotor loads and atmospheric boundary layer profiles.
Prerequisites
Recommended previous knowledge
MEK3230 – Fluid Mechanics, MEK3220 – Continuum Mechanics (discontinued)/MEK4220 – Continuum Mechanics (discontinued), MEK4330 – Turbulence theory and modeling/MEK9330 – Turbulence theory and modeling. It is an advantage to have taken MEK4420 – Marine Hydrodynamics/MEK9420 – Marine Hydrodynamics.
