Effects of Side Walls on Pipe Inlet Flow(Drag Reduction by Separated Flow Control Using Ring Shaped Small Obstacle)

open access: yesJournal of Fluid Science and Technology, 2009
The flow from a wide space into a pipe has a large annular separated vortex region just after the inlet corner. This vortex region produces large flow resistance, or drag, in this kind of flow.

Large eddy simulation of water flow over series of dunes

open access: yesWater Science and Engineering, 2011
Large eddy simulation was used to investigate the spatial development of open channel flow over a series of dunes. The three-dimensional filtered Navier-Stokes (N-S) equations were numerically solved with the fractional-step method in sigma coordinates ...

External Flow Separation

open access: yes, 2022
The flow transit from laminar to turbulent over the surface due to adverse pressure gradient, that the region in between the laminar separation and turbulent reattachment is called Laminar separation bubble. It experiences on the many engineering devices as well as controls the aerodynamic and heat transfer characteristics.

Boundary Layer Separation and Reattachment Detection on Airfoils by Thermal Flow Sensors

open access: yesSensors, 2012
A sensor concept for detection of boundary layer separation (flow separation, stall) and reattachment on airfoils is introduced in this paper. Boundary layer separation and reattachment are phenomena of fluid mechanics showing characteristics of ...

Field and flow-based separations [PDF]

open access: yesAnalytical and Bioanalytical Chemistry, 2015
Field-flow fractionation (FFF) and related methods are a set of analytical methods for the separation and characterization of nanoand micro-size analytes. These methods were originally used for the characterization of synthetic polymers and biological macromolecules, before also providing important contributions to the field of environmental sciences ...

Phase Separation Driven by Active Flows

open access: yesPhysical Review Letters, 2023
We extend the continuum theories of active nematohydrodynamics to model a two-fluid mixture with separate velocity fields for each fluid component, coupled through a viscous drag. The model is used to study an active nematic fluid, mixed with an isotropic fluid.

Novel Genetic Risk Factor Identified for L‐Asparaginase‐Induced Pancreatitis in Pediatric Patients With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.

Flow separation detector [PDF]

open access: yes, 1977
An arrangement for sensing the fluid separation along a surface which employs a thermally insulating element having a continuous surface blending into and forming a part of the fluid flow surface is described.
