Witryna13 kwi 2024 · Shi et al. ( Shi et al., 2024a) designed an axial-flow pump impeller based on the surface element method, and studied the influence of the impeller rotor on the hydraulic performance of the all-tube pump, and found that the reduction of the maximum running head of the all-tube pump was greater than that of the axial flow pump. Witryna--Jack Mamais, Director, Impeller Studios.
