A note on withdrawal from a two-layer fluid through a line sink in a porous medium
The steady response of the free surface of a fluid in a porous medium is considered during extraction of the fluid through a line sink. A conformal mapping approach is used to derive exact solutions to a family of problems in which the line sink is place at the apex of a wedge-shaped impermeable boundary, including the limiting cases of an ubounded aquifer and a flat-bottomed aquifer of finite ...
متن کاملa case study of the two translators of the holy quran: tahereh saffarzadeh and laleh bakhtiar
بطورکلی، کتاب های مقدسی همچون قران کریم را خوانندگان میتوان مطابق با پیش زمینه های مختلفی که درند درک کنند. محقق تلاش کرده نقش پیش زمینه اجتماعی-فرهنگی را روی ایدئولوژی های مترجمین زن و در نتیجه تاثیراتش را روی خواندن و ترجمه آیات قرآن کریم بررسی کند و ببیند که آیا تفاوت های واژگانی عمده ای میان این مترجمین وجود دارد یا نه. به این منظور، ترجمه 24 آیه از آیات قرآن کریم مورد بررسی مقایسه ای قرار ...
15 صفحه اولConvection from a line-source into a two-layer stratified ambient fluid
We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of λ, which represents the relative loss of buoyancy experienced by the plume upon crossing the ambient interface. When λ > 1,...
متن کاملBragg Resonances in a Two-layer Fluid
Equations are derived to approximately describe the propagation of small amplitude surface and interfacial waves across small irregularities in depth in a two-layer fluid. When the irregularities are sinusoidal, Bragg interaction effects between an incident surface wave and the bottom corrugations can lead to a large-amplitude reflected interfacial wave or a large-amplitude transmitted interfac...
متن کاملTrapped modes in a two-layer fluid
Abstract Trapped-mode frequencies are computed for submerged, horizontal, circular cylinders in a two-layer fluid consisting of a finite layer bounded above by a free surface and below by a infinite layer of greater density. Two separate cases are considered. First we consider waves which propagate along the top of a single cylinder at frequencies below the cut-off for wave propagation away fro...
