NUMERICAL INVESTIGATION OF FLOW IN MIXED-FLOW PUMP WITH VOLUTE

TASK Quarterly, 2001
This work deals with modelling of flow in a complete mixed-flow pump with volute, including the tip leakage flows, using both the quasi-steady and true transient models of rotor/stator interaction.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Factors Associated With the Rising Trend in Self‐Reported Cognitive Disability Among U.S. Adults Aged 18–39 From 2013–2024

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Building on our prior Behavioral Risk Factor Surveillance System analysis identifying adults aged 18–39 as the primary driver of the national increase in self‐reported cognitive disability, we examined factors associated with this rise using 2013–2024 U.S. BRFSS data. Methods We analyzed U.S.

Experimental study on the flow of a mixed flow pump impeller

IOP Conference Series: Earth and Environmental Science, 2012
Mixed flow pump is wildly used in many field, the performance of the whole pump is affected by the flow in the impeller to a great extend. To make clear the flow phenomena in the mixed flow impeller at design and off-design flow rate condition, a mixed flow unshrouded impeller was manufactured and the flow in the impeller at design and off-design flow ...

Rim Driven Thruster as Innovative Propulsion Element for Dual Phase Flows in Plug Flow Reactors

Fluids
The purpose of this work was to test a new setup to pump water with entrained air for application in gas fermentation. A mixed flow, where gas is contained in a liquid to be pumped, rapidly reduces the efficiency of a conventional pump, due to the ...
