An unsteady magnetohydromagnetic natural convection on the Couette flow of electrically conducting water at 4 0 C (Pr = 11.40) in a rotating system has been considered. A Finite Element Method (FEM) was employed to find the numerical solutions of the dimensionless governing coupled boundary layer partial differential equations. The primary velocity, secondary velocity and temperature of water at 4 o C as well as shear stresses and rate of heat transfer have been obtained for both ramped temperature and isothermal plates. The results are independent of the mesh (grid) size and the present numerical solutions through the Finite Element Method (FEM) are in good agreement with the existing analytical solutions by the Laplace Transform Technique (LTT). These are shown in tabular and graphical forms.

“…The influence of thermophysical properties of nanofluids on the convective heat transfer was presented by Dvangthongsule and Wongwises (2008). Steady boundary layer velocity and heat transfer for various types of nanofluids close to a vertical plate in the presence of heat generation was proposed by Rana and Bhargava (2011). Crane (1970) solved the problem of boundary layer flow of an incompressible viscous fluid past a stretching sheet analytically.…”

In our present study, the boundary layer flow of nanofluid over a porous stretching sheet due to presence of heat generation/absorption with effects of velocity slip condition and convective boundary condition using homotopy analysis method have been investigated. The fluid flow and heat transfer equations used for the analysis take care on the influence of suction and blowing parameter the permeability parameter of porous medium, Velocity slip parameter, convective Biot number, Heat generation/absorption parameter, Prandtl number, Brownian motion parameter, Thermophoresis parameter, and Lewis number. The solution for the velocity, temperature, and concentration of nanoparticle depends on parameters are analysis numerically and graphically. The governing equations which are non-linear boundary-layer equations are be transformed to couple of higher order non-linear ordinary differential equations using similarity transformation. This system is solved analytically using homotopy analysis method. An investigation has been carried out to show the influence of involved parameters corresponding to several physical conditions. Numeral data are obtained for profiles of velocity, temperature, and nanoparticle concentration for different values of involved parameters. A comparative analysis with previous studies published found in the literature and present results in a limiting case are found to be in excellent agreement.Keywords: Heat generation/absorption; Boundary layer slip flow; Porous sheet; HAM; Nanofluid; Suction; Blowing Nomenclature constants ( ) magnetic field applied magnetics induction

-This study reports experimental and Computational Fluid Dynamics (CFD) investigations of the laminar convective heat transfer coefficient of Al 2 O 3 /water nanofluids in a circular tube under uniform and constant heat flux on the wall. Three different models including a constant physical properties single-phase (CP-SP) model, a variable physical properties single-phase (VP-SP) model and a discrete particles two-phase model were developed. Particle agglomeration and cluster size distribution were considered in the two-phase model. Experimental and simulation results showed that the thermal performance of nanofluids is higher than that of the base fluid and the heat transfer enhancement increases with the particle volume concentration and Reynolds number. Furthermore, higher heat transfer coefficients were detected in the case of the VP-SP model and the two-phase model. The results demonstrated that the two-phase model prediction and experimental data match significantly and that the model can be employed with confidence for the prediction of any type of nanofluid.
