A new collocation scheme for solving hyperbolic equations of second order in a semi-infinite domain
ملخص البحث
This paper reports a new fully collocation algorithm for the numerical solution
of hyperbolic partial differential equations (PDEs) of second order in a semi-infinite domain,
using Jacobi rational Gauss-Radau collocation (JR-GR-C) method. The widely
applicable, efficiency, and high accuracy are the more advantages of the collocation
method. The series expansion in Jacobi rational functions is the main step for solving
the mentioned problems. The expansion coefficients are then determined by reducing
the hyperbolic equations with its boundary and initial conditions to a system of
algebraic equations for these coefficients. This system may be solved analytically or
numerically in step-by-step manner by using Newtons iterative method. Numerical results
are consistent with the theoretical analysis and indicating the high accuracy and
effectiveness of this algorithm.
