Study on the Dynamic Structure and Unsteady Characteristics of Vortex Flow for Blade Tip Clearance Leakage of a Single-vane Spiral Centrifugal Pump

Numerical simulations based on the RANS equations and the SST k‑ω turbulence model were carried out to study the turbulence characteristics in the tip clearance region of a spiral centrifugal pump. Results indicate that reducing the tip clearance significantly improves pump head and efficiency. At t...
