The steady-state fully-developed laminar flow of non-Newtonian power-law fluids is examined in a circular microchannel with slip boundary condition and under an imposed constant wall heat flux. Effects of slip as well as the hydrodynamic and thermal key parameters on heat transfer and entropy generation are investigated. The results reveal that increasing the Brinkman number and the flow behavi...

The present study encountered the impact of non-dimensional fusion temperature on free convection conducting nanofluid within a porous enclosure filled with nano-encapsulated phase change materials (NEPCMs). is equipped two parallel fins that have ability to move in both directions such as vertically well horizontally. In particular particles are structured core-shell materials. obtained from s...

Heat transfer phenomena of flat plate solar collector filled with different nanofluids has been investigated numerically. Galerkin’s Finite Element Method is used to solve the problem. Heat transfer rate, average bulk temperature, average sub-domain velocity, outlet temperature, thermal efficiency, mean entropy generation and Bejan number has been investigated by varying the solid nanoparticle ...

Heat and flow enhancement is a critical weapon for the design of highly efficient, compact, cost-effective devices. The objective this analysis detailed examination implementation different fin shapes on internal side tube aiming heat enhancement. reference empty examined, while use circular, rectangular, triangular fins also studied. Different simulations were conducted with developed computat...

In cooperative games, the core is one of the most popular solution concept since it ensures coalitional rationality. For non-balanced games however, the core is empty, and other solution concepts have to be found. We propose the use of general solutions, that is, to distribute the total worth of the game among groups rather than among individuals. In particular, the k-additive core proposed by ...

The characteristic of magnetohydrodynamic flow viscous fluids is explained here. energy equation behavior studied in the presence heat, dissipation, and joule heating. major emphasis this study physical entropy optimization rate. Based on implementation curvilinear coordinates, basic equations are established. Nonlinear partial differential expressions reduced by appropriate transformation to o...

Comparative zoologists, evolutionary biologists, experimental biologists, and mechanical engineers make wonderful generalizations about the movements of different-sized running bipeds and quadrupeds (Heglund et al., 1974; McMahon, 1975; Alexander, 1976; Hoyt & Taylor, 1981; Garland, 1982; McMahon et al., 1987; Rome et al., 1988; Gatesy & Biewener, 1991; Farley et al.,1993; Cynthia & Farley, 199...

Abstract In this article, we analyze the entropy analysis in unsteady hydromagnetic flow of a viscous fluid over stretching surface. The energy attribute is scrutinized through dissipation, heat source/sink, and radiation. Furthermore, diffusion-thermo thermo-diffusion behaviors are analyzed. physical description rate discussed second law thermodynamics. Additionally, binary chemical reaction c...

The paper aims to analyze the effects of various Prandtl number and different nanoparticles for heat transfer entropy generation free convection laminar fluid flow in an L-shaped cavity filled by nanofluid.
