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,

Direct Consolidation of Copper–Graphene Composite by Rotary Swaging

Advanced Engineering Materials, EarlyView.
The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

Experimental study of laminar separation phenomenon combining with numerical calculations

Vietnam Journal of Mechanics, 2011
The separation is much more sensitive for laminar flow than for turbulent flow. These remarks have been attested for both subsonic and supersonic flows.

How does flow in a pipe become turbulent?

, 2007
The transition to turbulence in pipe flow does not follow the scenario familiar from Rayleigh-Benard or Taylor-Couette flow since the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers.

Evaluation of the Edgegard Laminar Flow Hood [PDF]

Applied Microbiology, 1970
In a horizontal back-to-front flow high-efficiency particulate air-filtered laminar hood, it is shown that a Blake bottle obstruction to the air flow causes a downstream cone of turbulent air which can draw microbial contamination into the work area of the hood.

Laminar Flow Activation of ERK5 Protein in Vascular Endothelium Leads to Atheroprotective Effect via NF-E2-related Factor 2 (Nrf2) Activation*

Journal of Biological Chemistry, 2012
Background: Laminar flow protects from atherosclerosis in endothelium. Results: Laminar flow induces Nrf2 activation dependent on ERK5 activation, leading to up-regulation of downstream genes of Nrf2.

2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration

Advanced Functional Materials, EarlyView.
Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...

Numerical Study of Entropy Generation in a Flowing Nanofluid Used in Micro- and Minichannels

Entropy, 2013
This article mainly concerns theoretical research on entropy generation influences due to heat transfer and flow in nanofluid suspensions. A conventional nanofluid of alumina-water (Al2O3-H2O) was considered as the fluid model.

Convective Heat Transfer and Pressure Drop Characteristics of Graphene-Water Nanofluids in Transitional Flow [PDF]

arXiv, 2020
The convective heat transfer and flow behavior of graphene-water nanofluids are studied experimentally by focusing on transitional flow. Graphene-water nanofluids with different particle mass fractions (0.025, 0.1 and 0.2%) are produced following two-step method and using PVP as a surfactant.

Local numerical simulations of warped discs [PDF]

, 2018
We study the hydrodynamical stability of the laminar flows associated with warped astrophysical discs using numerical simulations of warped shearing boxes. We recover linear growth rates reported previously due to a parametric resonance of inertial waves, and show that the nonlinear saturated state can significantly reduce the laminar flows, meaning ...
