Pelton Wheel Jet Impulse Turbine (2D)

Interactive 2D Pelton wheel simulator: a high-velocity water jet strikes curved buckets on a spinning wheel. Adjust jet velocity, nozzle size, bucket deflection angle and generator load, and watch the live power-vs-bucket-speed curve peak at exactly half the jet speed.

This 2D side-view simulator models the same momentum-exchange physics as the 3D Pelton wheel: a free jet strikes curved buckets and is deflected through roughly 180° − β, and the wheel's angular velocity is integrated in real time from the net torque (jet impulse minus generator load). A live power-vs-bucket-speed curve is swept every frame from the instantaneous relative-velocity power formula, confirming numerically — for any jet velocity or deflection angle — that maximum power extraction always occurs at a bucket speed of exactly half the jet speed.

⚙ Under the hood

A high-velocity water jet strikes split buckets on a spinning Pelton runner; adjust head, nozzle size, bucket angle and generator load and watch the impulse force, wheel speed and hydraulic efficiency respond in real time.
