Optimization of the output device of a disk pump for high viscous fluid

Abstract

In this paper the problem of designing an output device for dynamic pumps operating at a high fluid viscosity on the example of a disk pump was considered. The main objective of the study was to increase the pump efficiency by optimizing the geometry of the wet part of its volute. The dependences of the efficiency on the geometrical parameters of the output device estimated section were obtained. The results of the study are represented in a form of graphs and scalar field distributions.

Comparative analysis of internal flow characteristics and particle trajectories of centrifugal pumps with different impeller structures under solid-liquid two-phase flow conditions

“…Wang et al [15] found through analysis that the main losses of the Tesla disc pump occur downstream of the impeller. Cheremushkin et al [16] optimized the volute of the Tesla disc pump model, resulting in the optimized model achieving better efficiency than the original model. Some scholars have studied the solid-liquid two-phase flow inside the bladed disc pump from different perspectives, mainly studied the influence of particle size, particle density, and particle concentration on the wear parts, particle concentration distribution, and head efficiency inside the pump.…”
