A comprehensive review on natural convection in various shaped enclosures by FEM: Engineering applications

South African Journal of Chemical Engineering
Natural convection within enclosed cavities plays a critical role in heat and mass transfer across a wide range of engineering applications. Buoyancy flows are a fundamental aspect of many optimized systems currently deployed, including passive cooling ...

Investigation of Fractional Behaviors for Physical Phenomena Equation and Ion-Acoustic Wave Equation via Generalized Bernoulli Equation Method

Computational and Mathematical Methods
This research explores the fractional dynamics of two important nonlinear models: the (2+1)-dimensional breaking soliton equation, which arises in the description of various physical phenomena such as shallow-water waves, plasma oscillations, and optical

Two-dimensional ring-like vortex and multisoliton nonlinear structures at the upper-hybrid resonance

, 2007
Two-dimensional (2D) equations describing the nonlinear interaction between upper-hybrid and dispersive magnetosonic waves are presented. Nonlocal nonlinearity in the equations results in the possibility of existence of stable 2D nonlinear structures.

Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6] [PDF]

, 2009
We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.

Spin-orbit coupled polariton condensates in a radially-periodic potential: Multiring vortices and rotating solitons

, 2018
We address evolution of a spinor polariton condensate in radially periodic potentials. Such potentials allow for the observation of novel nonlinear excitations and support a variety of dynamically stable soliton states never demonstrated before in ...

Effects of a localized beam on the dynamics of excitable cavity solitons [PDF]

, 2008
We study the dynamical behavior of dissipative solitons in an optical cavity filled with a Kerr medium when a localized beam is applied on top of the homogeneous pumping.

Diffraction-Attenuation Resistant Beams: their Higher Order Versions and Finite-Aperture Generations

, 2010
Recently, a method for obtaining diffraction-attenuation resistant beams in absorbing media was developed through suitable superposition of ideal zero-order Bessel beams. In this work, we will show that such beams maintain their resistance to diffraction
