Poincaré index formula and analogy with the Kosterlitz-Thouless transition in a non-rotated cold atom Bose-Einstein condensate

open access: yesJournal of High Energy Physics, 2022
A dilute gas of Bose-Einstein condensed atoms in a non-rotated and axially symmetric harmonic trap is modelled by the time dependent Gross-Pitaevskii equation.

The onset of modified Fourier and Fick’s theories in temperature-dependent conductivity flow of micropolar liquid

open access: yesResults in Physics, 2017
Nonlinear convective stagnation point flow of micropolar liquid is modeled. Stretching surface has variable thickness. Energy and concentration are modeled with modified Fourier and Fick’s relations.

The inflow in the Baltic Proper as recorded in January–February 2015

open access: yesOceanologia, 2016
Inflowing saline waters of the Major Baltic Inflow (MBI) in 2014 were recorded in the Baltic Proper in January 2015. After 12 years of stagnation, this inflow brought highly saline (about 20) waters into the Bornholm Basin.

Stagnation point flow of viscoelastic nanomaterial over a stretched surface

open access: yesResults in Physics, 2018
Present communication aims to discuss magnetohydrodynamic (MHD) stagnation point flow of Jeffrey nanofluid by a stretching cylinder. Modeling is based upon Brownian motion, thermophoresis, thermal radiation and heat generation.

Numerical simulation of heat transfer features in oblique stagnation-point flow of Jeffrey fluid

open access: yesAIP Advances, 2018
This article concentrates on the characteristics of heat transfer in oblique stagnation point flow of Jeffrey fluid deformed by a linear stretchable surface. The surface temperature is higher than that of the ambient fluid.

Effect of the stagnation temperature on the normal shock wave

open access: yesJournal of Computational Methods in Sciences and Engineering, 2009
When the stagnation temperature increases, the specific heat does not remain constant and start to vary with this temperature. The gas is perfect; its state equation remains always valid, except, it was called by calorically imperfect gas or gas at high temperature.
