Impeller diameter is a crucial design parameter of high-speed rescue pumps because it affects the performance and inner flow characteristics of these pumps.
In this study, a pump with an impeller diameter of 248 mm was modeled and its performance was tested.
Numerical simulations were conducted under steady and unsteady states, in which the sizes of the impeller diameters were designated as 248 mm (original), 235.6 mm (5% trimmed), 223.2 mm (10% trimmed), and 210.8 mm (15% trimmed).
ANSYS software was used to test the shear stress transport (SST k-ω) of the four models, and results agreed well with experimental data.
Diameter size affected impeller characteristics in both steady and unsteady states.
Subsequently, the differences in performance, hydraulic loss, pressure pulsation, and radial force of the impellers were evaluated.
In the performance test, the head and efficiency of the pump decreased as impeller diameter was reduced.
The result trends are in accordance with the trim law within the acceptable error range.
In terms of hydraulic loss, the impeller and diffuser vane components presented opposite trends with flow rate increase.
Finally, in terms of pressure pulsation and radial force, the amplitude diminished while periodicity improved as impeller diameter decreased.
