摘要

Hydrodynamic equations of the two-dimensional flow in an impeller row are used to derive the general form of an analytical expression for calculating the radial distribution of the axial and circumferential components of the absolute flow velocity behind the screw with a relative length of the blade channel of less than four equivalent diameters, under operating conditions of no inverse flows at the inlet or counterflows at the outlet. Adequate agreement is demonstrated between the experimental data and the results from calculating the axial component of the absolute flow velocity behind the screw using the suggested formula (disregarding the friction loss).
