چکیده
Article history: Received 13 June 2016 Accepted 14 July 2016 Available online 19 July 2016 The present article addresses the effects of convective heat transfer of nanofluid utilizing Buongiorno'smodel in a wavy channel. The simultaneous effects of Brownianmotion and thermophoresis are discussed. The solutions for velocity, temperature and concentration are analytically obtained. Effects of sundry parameters such as Lewis number Le, Prandtl number Pr, thermophoresis numberNt and Brownianmotion numberNb are graphically presented. The streamlines have also been shown to discuss the skin fiction with the different buoyancy discipline. Computations for hybrid Genetic Algorithm andNelder-Mead approach are also offered for the validity of obtained results. © 2016 Elsevier B.V. All rights reserved.

Experimental study of convective heat transfer coefficient of MgO nanofluid in a cylindrical microchannel heat sink
Convective heat transfer of MgO-water nanofluid in a microchannel heat sink is experimentally investigated in various concentrations of 0.01, 0.05, 0.1, and 0.6 wt%. The microchannel consisted of 48 parallel rectangular cross section channels with the height of 800 µm, width of 524 µm and length of 52 mm. A well stability duration (ca. 1 month) was resulted by a 180 min ultra-sonication of the ...
متن کاملNumerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel
Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

In this paper, natural convection heat transfer of CuO-water Nanofluid within a wavy-walled cavity and subjected to a uniform magnetic field is examined by adopting the lattice Boltzmann model. The left wavy wall is heated sinusoidal, while the right flat wall is maintained at the constant temperature of Tc. The top and the bottom horizontal walls are smooth and insulated against heat and mass....
