Modeling of entropy optimization for hybrid nanofluid MHD flow through a porous annulus involving variation of Bejan number. [PDF]

open access: yesSci Rep, 2020
AbstractWe numerically investigate the non-Darcy magnetohydrodynamic hybrid nanoparticle migration through a permeable tank using control volume finite element method through entropy generation. The roles of various amounts of Permeability, Lorentz and Rayleigh (Ra) number are investigated upon the various aspects of the hybrid nanofluid flow through ...

A Rare Case of Delayed Cerebral Air Embolism Occurring 7 H After Central Line Removal. [PDF]

open access: yesClin Case Rep
CT demonstrating scattered intracerebral air 7 h after central line removal. ABSTRACT Venous air embolism is a rare complication of central venous catheter insertion that can have devastating consequences. Delayed air entrainment may occur in the presence of fibrin sheath formation via reinforcement of a vein‐to‐dermis fistula, which can lead to air ...

Modeling Fluid dynamics and Aerodynamics by Second Law and Bejan Number (Part 1 - Theory) [PDF]

open access: yesINCAS Bulletin, 2019
Two fundamental questions are still open about the complex relation between fluid dynamics and thermodynamics. Is it possible (and convenient) to describe fluid dynamic in terms of second law based thermodynamic equations?

Entropy generation of MHD flow of sodium alginate (C6H9NAO7) fluid in thermal engineering

open access: yesScientific Reports, 2022
In this paper, impacts of magnetic field and porosity on the entropy generation of sodium-alginate (C6H9NaO7) fluid are studied. C6H9NaO7 is taken over a moving and heated vertical wall. Heat transfer is due to free convection.

An assessment of the mathematical model for estimating of entropy optimized viscous fluid flow towards a rotating cone surface

open access: yesScientific Reports, 2021
Entropy optimization in convective viscous fluids flow due to a rotating cone is explored. Heat expression with heat source/sink and dissipation is considered. Irreversibility with binary chemical reaction is also deliberated. Nonlinear system is reduced
