DRBEM solution of the Cauchy MHD duct flow with a slipping perturbed boundary
Aydin, Cemre; Tezer, Münevver (Elsevier BV, 2018-08-01)
In this study, the MHD flow direct and Cauchy problems are solved in a rectangular duct with a perturbed, curved, and slip upper boundary. The aim is to recompute the slipping velocity and the slip length by using the asymptotic analysis with respect to the perturbation parameter e and solving MHD flow equations for the first order and the corrector solutions in the rectangular duct. Hence, without discretizing the curved boundary, we are able to obtain the solution of MHD flow in the duct with curved pertu...
DRBEM Solution of MHD flow in a rectangular duct with time-varied external magnetic field
Ebren Kaya, Elif; Tezer, Münevver (Elsevier BV, 2020-08-01)
This paper investigates the flow behavior of a viscous, incompressible and electrically conducting fluid in a long channel subjected to a time-varied oblique magnetic field B-0(t) = B(0)f(t). The time-dependent MHD equations are solved by using the dual reciprocity boundary element method (DRBEM). The transient level velocity and induced magnetic field profiles are presented for moderate Hartmann number values, several direction of applied magnetic field and for several functions f(t) as polynomial, exponen...

DRBEM solution of mixed convection flow of nanofluids in enclosures with moving walls
Gumgum, S.; Tezer, Münevver (Elsevier BV, 2014-03-15)
This paper presents the results of a numerical study on unsteady mixed convection flow of nanofluids in lid-driven enclosures filled with aluminum oxide and copper-water based nanofluids. The governing equations are solved by the Dual Reciprocity Boundary Element Method (DRBEM), and the time derivatives are discretized using the implicit central difference scheme. All the convective terms and the vorticity boundary conditions are evaluated in terms of the DRBEM coordinate matrix. Linear boundary elements an...
DRBEM solution of the thermo-solutal buoyancy induced mixed convection flow problems
Alsoy-Akgun, Nagehan; Tezer, Münevver (Elsevier BV, 2013-03-01)
Mixed convective heat and solutal transport is important in engineering applications such as nuclear waste disposal, crystal growth and oceanography. Mixed convective in a lid-driven cavity and through channels with backward-facing step is studied by solving the equations of conservation of mass, momentum, energy and solutal concentration numerically. The governing equations are solved by using dual reciprocity boundary element method (DRBEM) with constant elements in terms of stream function, vorticity, te...
