Optimal design of vortex chamber pump

Abstract

The difficult operating conditions during the pumping of abrasive solid mediums lead to the rapid wear of the mechanical parts of the pumps. The use of jet pumps can significantly increase the reliability and durability of pumping equipment. However, direct-flow jet pumps have low efficiency. The use of the centrifugal force led to the creation of new jet pumps - vortex chamber pumps. Their performance indicators are better than direct-flow jet pump ones. The geometric parameters of the flow channel of the vortex chamber pumps were optimized. The study was carried out experimentally and numerically. Numerical simulation is based on solving the RANS equations with the shear stress transport turbulence model. The geometrical dimensions of the vortex chamber pump with the best performance indicators such as pressure and flow are found. The maximum achievable operating parameters of the vortex chamber pump are analyzed. The comparison of simulation results with experimental data is made.

Flow Modeling in a Vortex Chamber of a Liquid–Steam Jet Apparatus

“…Equation (19) does not consider the fractional-order Basset force. How on a droplet in a two-phase flow is valuable near the vibrational walls [32] in the considered design of the nozzle, all the walls are stationary.…”

Improving the Technical Level of Hydraulic Machines, Hydraulic Units and Hydraulic Devices using a Definitive Assessment Criterion at the Design Stage

“…The main problem of selection is that pumps of various types and manufacturers have almost the same coverage charts [16,17]. Also, proper pump selection is complicated by the possible use of jet pumps with low pressure, but high reliability and service life [18,19]. A similar situation is observed for other elements of hydraulic drives: motors and hydraulic units.…”

“…Передбачається, що висновки, зроблені щодо співвідношення розміру вимірювального інструменту і розміру вихрової камери або осьових каналів не залежатимуть від того, який саме робочий процес реалізує ВКН. Конструктивні особливості і характеристики насоса можна знайти в роботах [11,12,[14][15][16][17].…”
