This work looks at the two-dimensional MagnetoHydrodynamic steady slow flow of a conducting newtonian liquid about two solid insulating particles. It presents a powerful boundary approach to efficiently compute at a reasonable cpu time cost the flow about the particles when the imposed ambient uniform magnetic and the liquid velocity on each particle contour are given. The trick rests on two derived integral representations for the fluid velocity and pressure in the entire liquid domain. The task is thereby reduced to the treatment of four coupled regularized boundary-integral equations governing the Cartesian components of the surface traction on the cluster boundary. The whole proposed numerical implementation is convincingly tested against theoretical exact solutions for a 2-disk cluster.

Free-Space Fundamental Solution of a 2D Steady Slow Viscous MHD Flow Sellier, A.; AYDIN, SELÇUK HAN; Tezer, Münevver (2014-12-01) The fundamental free-space 2D steady creeping MHD flow produced by a concentrated point force of strength g located at a so-called source point x(0) in an unbounded conducting Newtonian liquid with uniform viscosity mu and conductivity sigma > 0 subject to a prescribed uniform ambient magnetic field B = Be-1 is analytically obtained. More precisely, not only the produced flow pressure p and velocity u but also the resulting stress tensor field sigma are expressed at any observation point x not equal x(0) in...
A Spectral Solenoidal-Galerkin Method for Rotating Thermal Convection between Rigid Plates Yıldırım, Cihan; Yarımpabuç, Durmuş; Tarman, Hakan I. (Hindawi Limited, 2013) The problem of thermal convection between rotating rigid plates under the influence of gravity is treated numerically. The approach uses solenoidal basis functions and their duals which are divergence free. The representation in terms of the solenoidal bases provides ease in the implementation by a reduction in the number of dependent variables and equations. A Galerkin procedure onto the dual solenoidal bases is utilized in order to reduce the governing system of partial differential equations to a system ...
A stabilized finite element method for the two-field and three-field Stokes eigenvalue problems Türk, Önder; Codina, Ramon (2016-10-01) In this paper, the stabilized finite element approximation of the Stokes eigenvalue problems is considered for both the two field (displacement pressure) and the three-field (stress displacement pressure) formulations. The method presented is based on a subgrid scale concept, and depends on the approximation of the unresolvable scales of the continuous solution. In general, subgrid scale techniques consist in the addition of a residual based term to the basic Galerkin formulation. The application of a stand...
A spectral Petrov-Galerkin method for thermal convection between rigid plates Yıldırım, Cihan; Tarman, Işık Hakan (2009-09-18) A numerical approach to the transition in the problem of thermal convection between rigid plates under the influence of gravity is presented. The approach uses solenoidal basis functions that satisfy the continuity equation and the boundary conditions under a Petrov-Galerkin procedure. A numerical experiment on the linear stability of thermal convection is performed to test the formulation and the implementation.
An investigation of x-ray escape for an HPGe detector Can, Cüneyt; Bilgici, SZ (Wiley, 2003-07-01) X-ray escape peaks for a planar HPGe detector were investigated for a point source of photons with 59.5 keV energy. The effect of the solid angle for the incident photons on the escape probability of Ge K x-rays was studied using collimators with varying apertures. A Monte Carlo program was also developed to estimate the probability of escape for various mechanisms and routes. The experimental and simulation results showed that the escape probability is essentially constant for a wide range of collimator ra...
