To investigate the motion patterns of flexible fibers inside a sewage pump and their impact on internal flow characteristics, visualization experiments were conducted to compare when transporting water—0.3% CMC solution 0.3% containing under different operating conditions. The results showed that changes in rheological properties primarily affected fluid viscous dissipation. Under same rotational speed, rate increased by only 2.4%, but power consumption decreased 9.1%, resulting 6.4% improvement efficiency. curvature distribution within impeller channel remained stable. Their was characterized an overall reduction velocity region, with peak decreasing up 26.3%. primary cause failure due tendency repeatedly accumulate detach at tongue, leading blockages. Fiber length had more significant blockage than mass concentration.

Vortex pumps are widely used in wastewater treatment, food processing, and the chemical industry. In this study, combined experimental numerical approaches employing rigid vorticity method were to investigate vortex structures flow characteristics within pump chamber. Quantitative analyses based on velocity moment, entropy production, energy distribution conducted elucidate evolution of transfer. Results indicate that run-through region sustains high-speed flow, whereas circulating generates toroidal transfer (TETV). Within region, TETV regulates direction enhances rotational but increases localized dissipation. Furthermore, is characterized by periodic dynamics, while demonstrates pronounced stability. Analysis transport equation underscores critical roles curl Coriolis terms transport. These findings enhance understanding phenomena pumps, provide a theoretical support for improving efficiency fluid systems.

To address the challenge of extracting dynamic features from nonlinear and non-stationary pressure pulsation signals (PPSs) in tubular pumps with blade attachments, while overcoming issues often associated traditional PPS processing methods, this study establishes a co-analytical algorithm by integrating Newton–Raphson-based optimizer guided feature mode decomposition Hilbert transform (HT). The principal conclusions derived can be summarized as follows: under high attachment area ratios (BAARs), disturbance effect attachments on flow pattern increases at Span = 0.50 0.95 impeller blades, surface velocity fluctuates obviously these positions. At monitoring points near hub middle outlet, PPSs exhibit sudden lower coefficients over time, point closer to rim side remain relatively stable. Under BAARs, number occurrences maximum amplitude HT spectrum same also increases. In addition, outlet has highest average standard deviation coefficient, reaching 0.0344.
