【 摘 要 】

In this paper a new Runge-Kutta method with minimal dispersion and dissipation error is developed. The Chebyshev pseudospectral method is utilized using spatial discretization and a new fourth-order six-stage Runge-Kurta scheme is used for time advancing. The proposed scheme is more efficient than the existing ones for acoustic computations. (C) 2004 Elsevier B.V. All rights reserved.
