Experimental and Theoretical Investigation of Water Jet Pump Performance [PDF]

International Journal of Applied Energy Systems, 2021
in this paper, we've experimentally and theoretically (analytical and numerical) investigated the water jet pump. The effect of operational and geometrical parameters on the water jet pump efficiency was determined experimentally and theoretically. The experimental investigation was held `firstly to work out the effect of driving nozzle spacing, area ...

Numerical studies for effect of geometrical parameters on water jet pump performance via entropy generation analysis

Journal of Mechanical Engineering and Sciences, 2023
This paper presented an implementation of entropy generation analysis in the main flow field of a water jet pump via the CFD method. This study aimed to identify the inefficient location of energy conversion and to analyse entropy generation sources in ...

Sediment Removal from Deep Reservoir Dams by Suction and Jet Flow [PDF]

E3S Web of Conferences, 2022
One method of sediment removal from dam reservoirs is the use of submerged pumps and suction mixes of sediment and water. This method is usually considered for shallow rivers but we want to adopt this method for large dams.

Development of Hybrid Airlift-Jet Pump with Its Performance Analysis

Applied Sciences, 2018
A new pump, called the hybrid airlift-jet pump, is developed by reinforcing the advantages and minimizing the demerits of airlift and jet pumps. First, a basic design of the hybrid airlift-jet pump is schematically presented.

Analysis of the Effect of in-Late Angle and Lower Valve Position in the Semi Jet Type Water Pump Installation Against Water Debit

Jurnal Serambi Engineering, 2023
The problem that often occurs in people who use semi-jet water pumps is that when the installation of the water pump has been completed, it turns out that the water discharge cannot flow as expected and the electricity consumption is quite large.

Derivation of near-optimal pump schedules for water distribution by simulated annealing [PDF]

, 2004
The scheduling of pumps for clean water distribution is a partially discrete non-linear problem with many variables. The scheduling method described in this paper typically produces costs within 1% of a linear program-based solution, and can incorporate ...
