Measured Impact Of Erosion On The Rotodynamic And Performance Characteristics Of A Mixed Flow ESP [PDF]

open access: yes, 2015
LectureThree stages of a mixed flow electric submersible pump were subjected to 117 hours of erosion using a 2 gram/liter concentration ratio of 100 mesh hydraulic fracture sand to water. The sand passed through the pump one time and is discarded.

Research on the Internal Flow Difference between Peak and Valley Conditions of Water Jet Propulsion Pump during Working at Hump Region

open access: yesJournal of Marine Science and Engineering
When we tested the water jet propulsion pump, we found that there were significant vibrations in the pump, especially at small flow points that deviated from the design conditions. The water jet propulsion pump is a mixed-flow pump with guide vane, which

Performance Evaluation and Dimensional Analysis of Multistage Helicoaxial Pump for Two-Phase Flow

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2019
A four stage helicoaxial pump was tested under varying operating conditions. A range of inlet pressures, rotational speeds (3000, 3600 rpm), and gas void fractures (GVFs) were considered for two fluid viscosities.

Numerical and experimental study of mixed flow pump as turbine for remote rural micro hydro power plant application

open access: yesJournal of Mechatronics, Electrical Power, and Vehicular Technology, 2022
The use of a pump as opposed to a turbine/pump as turbine (PAT) for off-grid electrification applications is one of the important ways to be considered in efforts to equalize electrical energy in Indonesia.

Hydrodynamic performance enhancement of a mixed-flow pump

open access: yesIOP Conference Series: Earth and Environmental Science, 2012
This paper presents an optimization procedure based on a radial basis neural network surrogate model for design of a vaned diffuser in a mixed-flow pump. Numerical analysis of fluid flow in a mixed-flow pump has been carried out by solving three-dimensional Reynolds-averaged Navier-Stokes equations with the shear stress transport turbulence model.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Research on the Non-uniform Flow Characteristics in a Screw Mixed-flow Deep-sea Mining Pump [PDF]

open access: yesJournal of Applied Fluid Mechanics
Deep-sea slurry pump is a crucial component for achieving vertical transportation of ore particles in pump-pipe lifting deep-sea mining systems. However, traditional mining pump structures face challenges, such as insufficient particle flow capacity and ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
