Tidal Turbine Power Coefficient

This simulator drives a real horizontal-axis tidal-stream turbine rotor through the same torque-balance physics that governs an actual seabed turbine: hydrodynamic torque from the current spins the rotor up, a generator load coefficient resists it, and the two settle onto an equilibrium tip-speed ratio λ. Power is computed from the standard C_p(λ, θ) rotor curve used in blade-element momentum theory, so changing current speed, blade pitch or generator load produces the same trade-offs a real turbine operator faces — including a seawater/air toggle that isolates exactly how much of a tidal turbine's compact size comes from water's far higher density.
