Numerical Solution of the Three-Dimensional Helmholtz Equation

引用

Chinese Physics Letters 2010年第6期27卷 1-4页

作者： syed tauseef Mohyud-Din Ahmet Ylldlrim Department of Basic Sciences HITEC University Taxila Cantt Pakistan Department of Mathematics Ege University 35100 Bornova-izmir Turkey

We apply the homotopy analysis method to solve the nonhomogeneous multidimensional partial differential equation model problem. The analytic solutions are calculated in terms of convergent series with easily computable components. The nonhomogeneous problem is quickly solved by observing the self-canceling ＂noise＂ terms whose sum vanishes in the limit. Numerical results clearly reveal the complete reliability and efficiency of the proposed algorithm.

作者： Ahmet Yildirim syed tauseef Mohyud-Din Department of Mathematics Ege University 35100 Bornova-Izmir Turkey HITEC University Taxila Cantt Pakistan

A scheme is developed to study numerical solution of the space- and time-fractional Burgers equations under initial conditions by the homotopy analysis method. The fractional derivatives are considered in the Caputo sense. The solutions are given in the form of series with easily computable terms. Numerical solutions are calculated for the fractional Burgers equation to show the nature of solution as the fractional derivative parameter is changed.
