Dynamics and Modelling of Fluidic Energy Devices

• Explain how the wind, waves and tides are formed, factors that influence their distribution and predictability
• Review the fundamental equations for fluid behaviour, characterisation of flow structures and forces and moments acting on lifting bodies
• Evaluate and select the most appropriate engineering performance model to undertake the simulation of a practical problem and critically assess the solution.

• Properties of fluids: Control volumes and fluid elements, Continuity, Momentum and Energy equations, stream function and velocity potential, Bernoulli’s equation
• Flow structures: Boundary layer theory, laminar and turbulent flow, steady and unsteady flow, flow breakdown and separations, vortex formation and stability
• Lifting flows: Circulation theory, Prandtl’s lifting-line theory, sources of drag, aerofoil characteristics
• Fluid loading on horizontal and vertical axis turbines.

Dynamics of floating bodies: from simple hydrostatics to complex dynamic response in waves:

• Hydrostatics of Floating Bodies; Buoyancy Forces and Stability, Initial stability, The wall sided formula and large angle stability, Stability losses, The Pressure Integration Technique
• Fluid loading on offshore structures and Ocean Waves Theory: The Added Mass Concept, Froude Krylov Force, Linear wave theory, Wave loading (Diffraction Theory & Morison Equation)
• Dynamics response of floating structures in waves: dynamic response analysis, application to floating bodies (buoys, semisub, TLP), effect of moorings.

• Induction factors (blade/blade-wake interactions), Pre- and Post-stall aerofoil characteristics, Dynamic stall models, Finite aspect ratio considerations, flow curvature model characterisation of near and far wakes, wake decay models, tidal array analysis.
