Extending the Bejan number to a general form
Thermal Science, 2013 A modified form of the Bejan number (Be), originally proposed by Bhattacharjee and Grosshandler for momentum processes, is obtained by replacing the dynamic viscosity (m) appearing in the original proposition with the equivalent product of the fluid density (r) and the momentum diffusivity of the fluid (n).

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

Correlations for Total Entropy Generation and Bejan Number for Free Convective Heat Transfer of an Eco-Friendly Nanofluid in a Rectangular Enclosure under Uniform Magnetic Field [PDF]
Processes, 2021 In this paper, focusing on the study of entropy generation (EGN), the convection flow of an eco-friendly nanofluid (N-F) in a rectangular enclosure is studied numerically. The nanoparticles (N-Ps) used are silver N-P, which are obtained in an eco-friendly manner from natural materials.

Thermal Science, 2021 This work is a continuation of the recent studies [1, 2], revealing that the unique form of the Bejan number is robust (unchangeable) and appears independently in all Hagen-Poiseuille fluid-flows with heat or mass transfer by convection. The other dimensionless groups, derived from the First law of thermodynamics (related to the convection ...

Entropy Generation and Bejan Number Analysis of MHD Casson Fluid Flow in a Micro-Channel with Navier Slip and Convective Boundary Conditions [PDF]
International Journal of Thermofluid Science and Technology, 2020 The analysis of MHD flow has been a concern of consideration for research scientists and engineers. In this treatise, the steady MHD flow of an incompressible and electrically conducting Casson fluid in a micro-channel with heat generation and viscous dissipation, in the presence of hydrodynamic slip and convective boundary conditions, is examined ...
