Laminar flow reduces cases of surgical site infections in vascular patients
Annals of the Royal College of Surgeons of England, 2013 Introduction Numerous strategies are employed routinely in an effort to lower rates of surgical site infections (SSIs). A laminar flow theatre environment is generally used during orthopaedic surgery to reduce rates of SSIs. Its role in vascular surgery,

Advanced Functional Materials, EarlyView.Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Natural laminar flow nacelle for transport aircraft [PDF]
The potential of laminar flow nacelles for reducing installed engine/nacelle drag was studied. The purpose was twofold: to experimentally verify a method for designing laminar flow nacelles and to determine the effect of installation on the extent of ...

Simplified Pressure Drop Model for Laminar Helical Flow of Power Law Fluid
Shiyou jixie, 2020 The theoretical models for predicting the pressure drop of the laminar helical flow of power-law fluids require tedious and complicated numerical calculations, which are difficult to directly apply to the field.

Advanced Functional Materials, EarlyView.Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Control-volume based Navier-Stokes equation solver valid at all flow velocities [PDF]
A control-volume based finite difference method to solve the Reynolds averaged Navier-Stokes equations is presented. A pressure correction equation valid at all flow velocities and a pressure staggered grid layout are used in the method. Example problems

Advanced Functional Materials, EarlyView.Flow through a nozzle is a common component of most fluid‐based polymer processing techniques such as spray drying, inkjet printing, extrusion. An ultrahigh molecular weight multi‐mechanophore system is used to probe the differences in the distribution of mechanical activation observed between nozzle flow and ultrasonication; the gold standard ...

Absolute linear instability in laminar and turbulent gas/liquid two-layer channel flow
, 2012 We study two-phase stratified flow where the bottom layer is a thin laminar liquid and the upper layer is a fully-developed gas flow. The gas flow can be laminar or turbulent.
