    High Frequency Diffraction of Cylindrical Waves by Perfectly Conducting Successive Step Discontinuities
    (Institute of Electrical and Electronics Engineers Inc., 2006) Türetken, B.; Alkumru, Ali; Büyükaksoy, A.; Kuştepeli, Alp
    The diffraction of high frequency cylindrical electromagnetic waves by step discontinuities is investigated rigorously by using the Fourier transform technique in conjunction with the mode matching method. The hybrid method of formulation gives rise to a scalar Wiener-Hopf equation of the third kind, the solution of which contains infinitely many constants satisfying infinite systems of linear algebraic equations.

    The Finite Element Method for Mhd Flow at High Hartmann Numbers
    (Elsevier Ltd., 2005) Neslitürk, Ali İhsan; Tezer, Münevver
    A stabilized finite element method using the residual-free bubble functions (RFB) is proposed for solving the governing equations of steady magnetohydrodynamic duct flow. A distinguished feature of the RFB method is the resolving capability of high gradients near the layer regions without refining mesh. We show that the RFB method is stable by proving that the numerical method is coercive even not only at low values but also at moderate and high values of the Hartmann number. Numerical results confirming theoretical findings are presented for several configurations of interest. The approximate solution obtained by the RFB method is also compared with the analytical solution of Shercliff's problem.
