Spectral Solution of Poisson Equation over Infinite Branched Channel
I. A. Ismail,G. Ismail,A. M. Sedqi 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.2
In this paper, we present a direct spectral collocation method for solving Poisson equation in polar coordinates. This equation is expressed spectrally over the unit circle. The resulting equation in spectral form is solved to give a solution to Poisson equation with Dirichlet boundary conditions at collocation points. The unit circle domain is conformally transformed to Y-geometry, retaining the value of the solution to give the solution of the same problem over Y-shape channel. Poisson equation can be solved similarly over many other geometries. The method is easy to implement, fast and gives spectral accuracy.
