The Dual Reciprocity Boundary Element Method For Magnetohydrodynamic Channel Flows, Song-Ping Zhu, Huan-Wen Liu Jan 2002

The Dual Reciprocity Boundary Element Method For Magnetohydrodynamic Channel Flows, Song-Ping Zhu, Huan-Wen Liu

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we consider the problem of the steady-state fully developed magnetohydrodynamic (MHD) flow of a conducting fluid through a channel with arbitrary wall conductivity in the presence of a transverse external magnetic field with various inclined angles. The coupled governing equations for both axial velocity and induced magnetic field are firstly transformed into decoupled Poisson-type equations with coupled boundary conditions. Then the dual reciprocity boundary element method (DRBEM) [20] is used to solve the Poisson-type equations. As testing examples, flows in channels of three different cross-sections, rectangular, circular and triangular, are calculated. It is shown that solutions obtained …


The Method Of Generalised Conditional Symmetries And Its Various Implementations, Joanna Goard Jan 2000

The Method Of Generalised Conditional Symmetries And Its Various Implementations, Joanna Goard

Faculty of Engineering and Information Sciences - Papers: Part A

We relate Kaptsov's method of B-determining equations for finding invariant solutions of PDEs to the nonclassical method and to the method of generalised conditional symmetries. An extension of Kaptsov's method is then used to find new solutions of degenerate diffusion equations.

A Novel Method For Loss Minimization In Distribution Networks, Kashem M. Muttaqi, Velappa Ganapathy, G B. Jasmon, M Buhari

Network reconfiguration for loss minimization is the determination of switching-options that minimizes the power losses for a particular set of loads on a distribution system. In this paper, a novel method is proposed by formulating an algorithm to reconfigure distribution networks for loss minimization. An efficient technique is used to determine the switching combinations, select the status of the switches, and find the best combination of switches for minimum loss. In the first stage of the proposed algorithm, a limited number of switching combinations is generated and the best switching combination is determined. In the second stage, an extensive search …
