The steady and laminar mixed convection flow of a viscous, incompressible, and electrically conducting fluid under the effect of an inclined magnetic field is numerically investigated. Specifically, the two-dimensional flow in a lid-driven cavity with a linearly heated wall is considered. The dual reciprocity boundary element method is used for solving the coupled nonlinear differential equations in terms of stream function, vorticity, and temperature. The study focuses on the effects of the physical parameters, such as Richardson and Hartmann numbers, on the flow field and the temperature distribution at different inclinations of the applied magnetic field. The streamlines and isotherms are used for the visualization of the flow and temperature fields. The code validations in terms of average Nusselt numbers show good agreement with the results given in the literature.

DRBEM solution to ferrofluid flow and heat transfer in semi annulus enclosure in the presence of magnetic field
Oğlakkaya, Fatma Sidre; Bozkaya, Canan (null; 2016-07-11)
In this work, ferrofluid flow and heat transfer in a semicircular annulus enclosure filled with Fe3O4- water nanaofluid is studied in the presence of an externally applied magnetic field. The inner and outer circular walls are maintained at constant temperature and two straight boundaries at the bottom are considered adiabatic. The governing equations which are consistent with the principles of ferrohydrodynamics (FHD) and magnetohydrodynamics (MHD) are discretized by using the dual reciprocity boundary ele...
DRBEM solution of biomagnetic fluid flow and heat transfer in cavities-CMMSE2016
Senel, P.; Tezer, Münevver (2017-08-01)
In this paper, we investigate the fully developed, laminar, forced convection flow of an electrically non-conducting, viscous, biomagnetic fluid in the 2D cross-section (cavity) of a long impermeable pipe. The fluid is under the influence of a point magnetic source placed below the cavity. The dual reciprocity boundary element method (DRBEM) with constant and linear elements is used for solving the governing equations resulting from the Navier-Stokes and energy equations together with magnetization and buoy...
DRBEM Solution of Incompressible MHD Flow with Magnetic Potential
Pekmen, B.; Tezer, Münevver (2013-12-01)
The dual reciprocity boundary element method (DRBEM) formulation is presented for solving incompressible magnetohydrodynamic (MHD) flow equations. The combination of Navier-Stokes equations of fluid dynamics and Maxwell's equations of electromagnetics through Ohm's law is considered in terms of stream function, vorticity and magnetic potential in 2D. The velocity field and the induced magnetic field can be determined through the relations with stream function and magnetic potential, respectively. The numeri...
DRBEM Solution for Unsteady Natural Convection Flow in Primitive Variables with Fractional Step Time Advancement
Sariaydin, A.; Tezer, Münevver (2012-07-14)
In this study, two-dimensional, transient flow of an incompressible, laminar, viscous fluid in a cavity is considered with the occurance of heat flux (temperature is not constant). The governing equations which are continuity, momentum and energy equations, define natural convection in differentially heated cavities in terms of primitive variables (velocities, temperature, and pressure). The no-slip condition for the velocity is imposed on the cavity walls. Left and right walls are heated and cooled, respec...
BEM solution to magnetohydrodynamic flow in a semi-infinite?duct
Bozkaya, Canan; Tezer, Münevver (2012-09-30)
We consider the magnetohydrodynamic flow that is laminar and steady of a viscous, incompressible, and electrically conducting fluid in a semi-infinite duct under an externally applied magnetic field. The flow is driven by the current produced by a pressure gradient. The applied magnetic field is perpendicular to the semi-infinite walls that are kept at the same magnetic field value in magnitude but opposite in sign. The wall that connects the two semi-infinite walls is partly non-conducting and partly condu...
