Numerical simulation and experimental study on hydraulic instability of pump as turbine devices induced by thoma number based on scale-averaged wavelet spectrum

Low-head hydropower resources are widely distributed, water-rich, and readily exploitable clean renewable energy sources. However, low-head pumps as turbines (PAT) unit often encounter challenges such as flow instability, significant cavitation, and output power fluctuations when operating under off...
