Abstract EN
This study simulates the flow through an impulse-type small-scale hydraulic turbine utilizing a waterfall of extra-low head.
The two-dimensional Moving Particle Semi-implicit (MPS) method is employed for the simulation.
The fluid is discretized by particles, and the flow is computed by the Lagrangian calculation for the particle motion.
When the distance between the particles discretizing the waterfall of a width B, l0, is set at l0/B≤0.084, the flow can be simulated with the sufficiently high spatial resolution, and the rotor performance can also be favorably predicted.
The present simulation also successfully analyzes the effect of the rotational speed of rotor on the flow and the turbine performance.
