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

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

Hydrodynamic performance enhancement of a mixed-flow pump
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.

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