For more than 20 years, the use of nanofluids to enhance heat transfer in microchannel sinks (MCHSs) has been subject a large number scientific articles. Despite great potentialities reported several works, presence controversial results and lack understanding enhancement mechanisms prevent further advancement as coolants. This article reviews literature focused on aspects that have role within...

in this paper, a new approach is proposed for the optimum design of single-phase induction motor. by using the classical design equations and the evolutionary algorithms such as genetic algorithms (ga), particle swarm optimization (pso) and modified particle swarm optimization (mpso), a single phase induction motor (spim) was designed with the maximum efficiency. the finite element method (fem)...

The efficiency of two-phase closed thermosyphon (TPCT) with nanofluid as working fluid under magnetic field effect was investigated experimentally. In this study, silver/water nanofluid with different concentration (20 to 80ppm) is tested. Also, magnetic field with various strength (0.12, 0.35 and 1.2 T) exerted to TPCT by permanent magnet. It was seen that the TPCT heat transfer performance an...

The influence of Coriolis body force, electro-magnetohydrodynamics (EMHD) and thermal radiative heat transfer on the Casson hybrid mixed convection nanofluid driven by an exponentially accelerated plate adjacent to a porous medium in rotating system is analyzed. Hybrid (Ag- Al2O3) Al2O3nanofluids are considered with ethylene glycol (EG) base fluid. Maxwell-Garnett model has been deployed derive...

This paper addresses entropy generation in the flow of an electrically-conducting couple stress nanofluid through a vertical porous channel subjected to constant heat flux. By using the Buongiorno model, equations for momentum, energy, and nanofluid concentration are modelled, solved using homotopy analysis and furthermore, solved numerically. The variations of significant fluid parameters with...

Output performance of a thermoelectric-based automotive waste heat recovery system with a nanofluid coolant is analyzed in this study. Comparison between Cu-Ethylene glycol (Cu-EG) nanofluid coolant and ethylene glycol with water (EG-W) coolant under equal mass flow rate indicates that Cu-EG nanofluid as a coolant can effectively improve power output and thermoelectric conversion efficiency for...

Considering interaction forces (gravity and buoyancy force, drag force, interaction potential force, and Brownian force) between nanoparticles and a base fluid, a two-phase Lattice Boltzmann model for natural convection of nanofluid is developed in this work. It is applied to investigate the natural convection in a square enclosure (the left wall is kept at a high constant temperature (TH), and...
