    Galerkin method for the numerical solution of the RLW equation using quadratic B-splines
    (TAYLOR & FRANCIS LTD, 2004) Saka, B; Dag, I; Dogan, A
    A numerical solution of the Regularised Long Wave (RLW) Equation is obtained using space-splitting technique and quadratic B-spline Galerkin finite element method. Solitary wave motion, interaction of two solitary waves and wave generation are studied using the proposed method. Comparisons are made with analytical solutions and with some spline finite element method calculations at selected times. Accuracy and efficiency are discussed by computing the numerical conserved laws and L-2, L-infinity norms.

    Numerical integration of the RLW equation using cubic splines
    (CAMBRIDGE UNIV PRESS, 2005) Irk, D; Dag, W; Dogan, A
    A numerical solution of the RLW equation is presented using a cubic spline collocation method. Basic cubic spline relations are outlined and incorporated into the numerical solution procedure. Two test problems are studied to show the robustness of the proposed procedure.

    Numerical investigation of heat and mass transfer in a metal hydride bed
    (ELSEVIER SCIENCE INC, 2004) Dogan, A; Kaplan, Y; Veziroglu, TN
    This paper presents a mathematical model for hydrogen storage in a metal hydride bed. For this purpose, a two-dimensional mathematical model which considers complex heat and mass transfer during the hydriding process is developed. The coupled differential equations are solved with a numerical method based on integrations of governing equation over finite control volumes. The driving force is considered to be pressure difference because of the temperature distribution in the system. The numerical results showed that the hydriding performance depends on the temperature distribution in the hydride bed. Fluid flow enhances the hydriding rate in the system by driving the hot fluid to the colder regions. The numerical results were found to agree satisfactorily with the experimental data available in the literature. (C) 2003 Elsevier Inc. All rights reserved.
