A DRBEM Approach for the STOKES Eigenvalue Problem
Tezer, Münevver; Türk, Önder (2016-07-04)
In this study, we propose a novel approach based on the dual reciprocity boundary element method (DRBEM) to approximate the solutions of various Steklov eigenvalue problems. The method consists in weighting the governing differential equation with the fundamental solutions of the Laplace equation where the definition of interior nodes is not necessary for the solution on the boundary. DRBEM constitutes a promising tool to characterize such problems due to the fact that the boundary conditions on part or all...
A Lagrangean relaxation approach for the mixed-model flow line sequencing problem
Eliiyi, Deniz Tuersel; Oezlen, Melih (Elsevier BV, 2008-03-01)
In this study, a mixed-model flow line sequencing problem is considered. A mixed-model flow line is a special case of production line where products are transported on a conveyor belt, and different models of the same product are intermixed on the same line. We have focused on product-fixed, rate-synchronous lines with variable launching. Our objective function is minimizing makespan. A heuristic algorithm based on Lagrangean relaxation is developed for the problem, and tested in terms of solution quality a...
A variational approach for the two-dimensional magnetopolaron
Erçelebi, Atila; Saqqa, Bassam H. (IOP Publishing, 1989-12-18)
The problem of a two-dimensional magnetopolaron is investigated on the basis of a variational theory consisting of an adiabatic polaronic wavefunction combined with a perturbative correction by which it is possible to interrelate the strong and weak coupling counterparts of the coupled electron-phonon system. It is seen that the theory conveniently reproduces the desirable asymptotic limits in the different regimes of the problem. Furthermore, it is suggested that a satisfying improvement should be achieved...
A viscous-inviscid interaction method for 2-D unsteady, compressible flows
Tuncer, İsmail Hakkı; Platzer, Max F. (1993-01-01)
© 1993 American Institute of Aeronautics and Aerodynamics, Inc. All rights reserved.A Navier-Stokes/potential flow interactive solution method suitable for the solution of steady-state and unsteady flowfields around airfoils has been developed. The Navier-Stokes equations are solved in the close proximity of an airfoil and in its wake. The inviscid flowfield surrounding the viscous flow regions is assumed to be irrotational and isentropic. In the inviscid flow region, the potential flow equations, which are...
