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 ...

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.

Gliding swifts attain laminar flow over rough wings. [PDF]
PLoS ONE, 2014 Swifts are among the most aerodynamically refined gliding birds. However, the overlapping vanes and protruding shafts of their primary feathers make swift wings remarkably rough for their size.

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 ...

Drag Reduction by Laminar Flow Control [PDF]
Energies, 2018 The Energy System Transition in Aviation research project of the Aeronautics Research Center Niedersachsen (NFL) searches for potentially game-changing technologies to reduce the carbon footprint of aviation by promoting and enabling new propulsion and drag reduction technologies. The greatest potential for aerodynamic drag reduction is seen in laminar

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.
