DRBEM Solution of the Double Diffusive Convective Flow Bozkaya, Canan; Tezer, Münevver (2015-09-18) A numerical investigation of unsteady, two-dimensional double diffusive convection flow through a lid-driven square enclosure is carried on. The left and bottom walls of the enclosure are either uniformly or non-uniformly heated and concentrated, while the right vertical wall is maintained at a constant cold temperature. The top wall is insulated and it moves to the right with a constant velocity. The numerical solution of the coupled nonlinear differential equations is based on the use of dual reciprocity ...
DRBEM SOLUTION OF THE NATURAL CONVECTIVE FLOW OF MICROPOLAR FLUIDS Gumgum, S.; Tezer, Münevver (Informa UK Limited, 2010-01-01) The main purpose of this article is to present the use of the dual reciprocity boundary element method (DRBEM) in the analysis of the unsteady natural convective flow of micropolar fluids in a differentially heated rectangular cavity. The finite-difference method (FDM) is used for time discretization. All the convective terms and vorticity boundary condition are evaluated in terms of DRBEM coordinate matrix. Solutions are obtained for several values of microstructure parameter (k), Rayleigh number (Ra), and...
DRBEM solution of the cauchy problem for MHD rectangular duct flow Aydın, Cemre; Tezer, Münevver (null; 2017-04-27) This study presents MHD rectangular duct flow as a Cauchy problem with overdetermined and underdetermined condi tions on the opposite parts of the duct walls. The governing coupled convection - diffusion type equations are solved using the dual reciprocity boundary element method (DRBEM). The problem is reformulated as an inverse problem by using the direct solution a nd solved with Tikhonov regularization. The optimal parameter is computed from the L - curve procedur...
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 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...
