Turbulent dispersion in cloud-topped boundary layers [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Compared to dry boundary layers, dispersion in cloud-topped boundary layers has received less attention. In this LES based numerical study we investigate the dispersion of a passive tracer in the form of Lagrangian particles for four kinds of atmospheric

Experimental Flow Field Investigation of the Bio-Inspired Corrugated Wing for MAV Applications [PDF]

open access: yesINCAS Bulletin, 2021
This is an experimental flow field study of a bio-inspired corrugated finite wing from the dragonfly intended to assess the flow behavior over the wing and compare it with a wing of the same geometry with filled corrugation, at low Reynolds numbers 46000

Effects of Internal Boundary Layers and Sensitivity on Frequency Response of Shells of Revolution

open access: yesVibration, 2023
New applications introduced capsule designs with features that have not been fully analysed in the literature. In this study, thin shells of revolution are used to model drug delivery capsules both with closed and open designs including perforations. The

A nonstandard fitted operator finite difference method for two-parameter singularly perturbed time-delay parabolic problems

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
In this article, a class of singularly perturbed time-delay two-parameter second-order parabolic problems are considered. The presence of the two small parameters attached to the derivatives causes the solution of the given problem to exhibit boundary ...

Effects of Surface Roughness on Shock-Wave/Turbulent Boundary-Layer Interaction at Mach 4 over a Hollow Cylinder Flare Model

open access: yesFluids, 2022
Although it is understood that surface roughness can impact boundary layer physics in high-speed flows, there has been little research aimed at understanding the potential impact of surface roughness on high-speed shock-wave/boundary-layer interactions ...

The theoretical model of interaction between the baroclinic boundary layers of atmosphere and ocean

open access: yesVietnam Journal of Mechanics, 1980
Presenting the theoretical model of the atmospheric and oceanic baroclinic boundary layers by interaction. Baroclinic effects of two boundary layers are described by the horizontal gradients of air temperature and water density in the equations of ...

Boundary-field-driven control of discontinuous phase transitions on hyperbolic lattices [PDF]

open access: yes, 2016
The multistate Potts models on two-dimensional hyperbolic lattices are studied with respect to various boundary effects. The free energy is numerically calculated by Corner Transfer Matrix Renormalization Group method. We analyze phase transitions of the

Error estimations of a weak Galerkin finite element method for a linear system of $ \ell\geq 2 $ coupled singularly perturbed reaction-diffusion equations in the energy and balanced norms

open access: yesAIMS Mathematics, 2023
This paper introduces a weak Galerkin finite element method for a system of $ \ell\geq 2 $ coupled singularly perturbed reaction-diffusion problems. The proposed method is independent of parameter and uses piecewise discontinuous polynomials on interior ...
