Flat bubble regime and laminar plasma flow in a plasma wakefield accelerator

open access: yesPhysical 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.

On the stationary Navier-Stokes flow with isotropic streamlines in all latitudes on a sphere or a 2D hyperbolic space [PDF]

open access: yes, 2013
In this paper, we show the existence of real-analytic stationary Navier-Stokes flows with isotropic streamlines in all latitudes in some simply-connected flow region on a rotating round sphere.

Contactless Localization of Premature Laminar–Turbulent Flow Transitions on Wind Turbine Rotor Blades in Operation

open access: yesApplied Sciences, 2020
Thermographic flow visualization enables a noninvasive detection of the laminar–turbulent flow transition and allows a measurement of the impact of surface erosion and contamination due to insects, rain, dust, or hail by quantifying the amount of laminar

Characterizing pulsatile blood flow in a specific carotid bifurcation: insights into hemodynamics and rheology models

open access: yesAIMS Biophysics, 2023
This study uses laminar and turbulent flow models to investigate the blood flow dynamics in a specific carotid bifurcation. Pulsatile boundary conditions and the rigid carotid artery wall are considered.

Turbulence via Intermolecular Potential: Viscosity and Transition Range of the Reynolds Number

open access: yesFluids, 2023
Turbulence in fluids is an ubiquitous phenomenon, characterized by spontaneous transition of a smooth, laminar flow to rapidly changing, chaotic dynamics.

Laminar, turbulent, and inertial shear-thickening regimes in channel flow of neutrally buoyant particle suspensions. [PDF]

open access: yesPhysical Review Letters, 2014
The aim of this Letter is to characterize the flow regimes of suspensions of finite-size rigid particles in a viscous fluid at finite inertia. We explore the system behavior as a function of the particle volume fraction and the Reynolds number (the ratio

Experimental Study on Liquid Flow and Heat Transfer in Rough Microchannels

open access: yesAdvances in Condensed Matter Physics, 2019
Although roughness is negligible for laminar flow through tubes in classic fluid mechanics, the surface roughness may play an important role in microscale fluid flow due to the large ratio of surface area to volume.
