The hydromagnetic free convection of a Cu-water nanofluid in a square cavity involving an adiabatic circular cylinder is numerically investigated in the presence of an inclined uniform magnetic field. The left and right walls of the cavity are kept at constant hot and cold temperatures, respectively, while the horizontal walls are assumed to be adiabatic. The coupled nonlinear equations of mass, momentum and energy governing the present problem are discretized using the dual reciprocity boundary element method which is a boundary only nature technique treating the nonlinear terms by the use of radial basis functions. The flow and thermal fields are analyzed through streamline, isotherm, and average Nusselt number plots for a wide range of controlling parameters, such as Rayleigh and Hartmann numbers, the nanoparticle volume fraction and the inclination angle of the magnetic field. The results reveal that heat transfer and fluid flow are strongly affected by the presence of the circular cylinder and the inclined magnetic field. © 2016, North Atlantic University Union NAUN.

FEM solution to natural convection flow of a micropolar nanofluid in the presence of a magnetic field TÜRK, ÖNDER; Tezer, Münevver (2017-03-01) The two-dimensional, laminar, unsteady natural convection flow in a square enclosure filled with aluminum oxide ()-water nanofluid under the influence of a magnetic field, is considered numerically. The nanofluid is considered as Newtonian and incompressible, the nanoparticles and water are assumed to be in thermal equilibrium. The mathematical modelling results in a coupled nonlinear system of partial differential equations. The equations are solved using finite element method (FEM) in space, whereas, the ...
Numerical investigation of unsteady natural convection from a heated cylinder in a square enclosure Bozkaya, Canan (null; 2015-07-06) A numerical study of two dimensional, unsteady, incompressible natural convection flow and heat transfer is performed in a square enclosure involving a heated circular cylinder. The natural convection is driven by a temperature difference between the cold outer square and hot inner circular cylinders. The temperature of the inner cylinder varies sinusoidally with time about a fixed mean temperature while the outer enclosure is kept at a lower constant temperature. The problem under consideration, which is g...
MHD natural convection flow in a porous cavity Bozkaya, Canan (null; 2018-09-13) A numerical investigation of natural convection flow in a cavity filled with a fluid-saturated porous medium in the presence of uniform magnetic field is performed. The steady, viscous, incompressible flow inside the porous medium is assumed to obey the Darcy law. The fluid physical properties are constant except the density in the body force term which is treated according to Boussinesq approximation. The fluid and porous medium are in thermal equilibrium. The governing equations subject to appropriate bou...
Natural convection flow of a nanofluid in an enclosure under an inclined uniform magnetic field Tezer, Münevver; Bozkaya, Canan (2016-01-01) In this study, the natural convection in a square enclosure filled with water-based aluminium oxide (Al2O3) under the influence of an externally applied inclined magnetic field is considered numerically. The flow is steady, two-dimensional and laminar; the nanoparticles and water are assumed to be in thermal equilibrium. The governing equations are solved in terms of stream function-vorticity-temperature using both the dual reciprocity boundary element method and the finite element method to see the influen...
RBF Solution of Incompressible MHD Convection Flow in a Pipe Gürbüz, Merve; Tezer, Münevver (2016-10-12) The steady convection flow of a viscous, incompressible and electrically conducting fluid is considered in a lid-driven cavity under the effect of a uniform horizontally applied magnetic field. The governing equations are the Navier-Stokes equations of fluid dynamics including buoyancy and Lorentz forces and the energy equation including Joule heating and viscous dissipation. These coupled equations are solved iteratively in terms of velocity components, stream function, vorticity, pressure and temperature ...
