Исследование структуры потока и прогнозирование характеристик секционного центробежного насоса низкой быстроходности

Calculated research of flow and hydraulic qualities of the multistage centrifugal pump with rapidity factor ns=40 is conducted. Methods of calculation of spatial viscous current are used. Results of calculation are compared with available experimental data. Good convergence of calculation with experiment is received. Updating of initial variant of the flowing part, possessing the best hydraulic qualities is developed.
