Intermittency, Moments, and Friction Coefficient during the Subcritical Transition of Channel Flow [PDF]

open access: yesEntropy, 2020
The intermittent distribution of localized turbulent structures is a key feature of the subcritical transitions in channel flows, which are studied in this paper with a wind channel and theoretical modeling.

One-dimensional numerical calculation for unsteady gas-liquid flow in micro channels with air gaps

open access: yesJournal of Fluid Science and Technology, 2021
A numerical calculation model for gas-liquid unsteady two-phase flow in a micro channel was established and validated. The model focuses on flow in a channel including air gaps.

Magnetohydrodynamic Flow of a Bingham Fluid in a Vertical Channel: Mixed Convection

open access: yesFluids, 2021
In this paper, we describe our study of the mixed convection of a Boussinesquian Bingham fluid in a vertical channel in the absence and presence of an external uniform magnetic field normal to the walls.

Thermal and Phase Change Process in a Locally Curved Open Channel Equipped with PCM-PB and Heater during Nanofluid Convection under Magnetic Field

open access: yesMathematics, 2022
Thermal performance and phase-change dynamics in a channel having a cavity equipped with a heater and phase-change material (PCM)-packed bed (PB) region are analyzed during nanoliquid convection under an inclined magnetic field.

Relative Effects of Asymmetry and Wall Slip on the Stability of Plane Channel Flow

open access: yesFluids, 2017
The effect of wall velocity slip on the stability of a pressure-driven two-dimensional asymmetric channel flow is examined by considering Navier slip condition on the channel walls.

Velocity Measurements in Channel Gas Flows in the Slip Regime by means of Molecular Tagging Velocimetry

open access: yesMicromachines, 2020
Direct measurements of the slip velocity in rarefied gas flows produced by local thermodynamic non-equilibrium at the wall represent crucial information for the validation of existing theoretical and numerical models.
