Unified Friction Formulation from Laminar to Fully Rough Turbulent Flow [PDF]
Applied Sciences, 2018 This paper provides a new unified formula for Newtonian fluids valid for all pipe flow regimes from laminar to fully rough turbulent flow. This includes laminar flow; the unstable sharp jump from laminar to turbulent flow; and all types of turbulent ...

Surface Cleanliness Maintenance with Laminar Flow Based on the Characteristics of Laser-Induced Sputtering Particles in High-Power Laser Systems [PDF]
Micromachines, 2023 In high-power laser systems, the primary cause of contamination of optical components and degradation of spatial cleanliness is laser-induced sputtering of particles.

Flat bubble regime and laminar plasma flow in a plasma wakefield accelerator [PDF]
Physical Review Accelerators and Beams, 2022 A simple 2D model of the bubble formation in a plasma wakefield accelerator is developed and investigated. We show that in the case of a flat driver, the bubble may consist of two parts.

Laminar flow substantially affects the morphology and functional phenotype of glomerular endothelial cells. [PDF]
PLoS ONE, 2021 Shear stress induced by laminar blood flow has a profound effect on the morphology and functional phenotype of macrovascular endothelial cells. The influence of laminar flow on the glomerular microvascular endothelium, however, remains largely elusive ...

Invariant Solution underlying Oblique Stripe Patterns in Plane Couette Flow [PDF]
, 2018 When subcritical shear flows transition to turbulence, laminar and turbulent flow often coexists in space, giving rise to turbulent-laminar patterns. Most prominent are regular stripe patterns with large-scale periodicity and oblique orientation. Oblique stripes are a robust phenomenon, observed in experiments and flow simulations, yet their origin ...

Absolute linear instability in laminar and turbulent gas/liquid two-layer channel flow [PDF]
arXiv, 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. To determine the boundary between convective and absolute instability, we use Orr--Sommerfeld stability theory, and a combination of linear modal analysis and ray analysis.

Mean flow of turbulent-laminar patterns in plane Couette flow [PDF]
J. Fluid Mech. 576, 109-137 (2007), 2007 A turbulent-laminar banded pattern in plane Couette flow is studied numerically. This pattern is statistically steady, is oriented obliquely to the streamwise direction, and has a very large wavelength relative to the gap. The mean flow, averaged in time and in the homogeneous direction, is analysed.

Rheology of sediment transported by a laminar flow. [PDF]
Phys Rev E, 2016 Understanding the dynamics of fluid-driven sediment transport remains challenging, as it is an intermediate region between a granular material and a fluid flow. Boyer \textit{et al.}\citep{Boyer2011} proposed a local rheology unifying dense dry-granular and viscous-suspension flows, but it has been validated only for neutrally-buoyant particles in a ...

Progress in research of non-drug interventions for cancer-related fatigue (肿瘤患者癌因性疲乏非药物干预的研究进展)
中西医结合护理, 2022 Due to the subjective and persistent nature of cancer-related fatigue (CRF), the correct assessment, treatment and care of CRF symptoms in cancer patients has gradually been recognized as an important aspect of cancer follow-up treatment.
