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 ...

Graph neural networks for laminar flow prediction around random two-dimensional shapes [PDF]
The Physics of Fluids, 2021 In the recent years, the domain of fast flow field prediction has been vastly dominated by pixel-based convolutional neural networks. Yet, the recent advent of graph convolutional neural networks (GCNNs) have attracted a considerable attention in the ...

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.

Front propagation in laminar flows [PDF]
Physical Review E, 2001 The problem of front propagation in flowing media is addressed for laminar velocity fields in two dimensions. Three representative cases are discussed: stationary cellular flow, stationary shear flow, and percolating flow. Production terms of Fisher-Kolmogorov-Petrovskii-Piskunov type and of Arrhenius type are considered under the assumption of no ...
