An efficient upwind/relaxation algorithm for the Euler and Navier–Stokes equations

An efficient Euler and full Navier–Stokes solver based on a flux splitting scheme is presented. The original Van Leer flux vector splitting form is extended to arbitrary body-fitted co-ordinates in the physical domain so that it can be used with a finite volume scheme. The block matrix is inverted by Gauss–Seidel iteration. It is verified that the often used reflection boundary condition will produce incorrect flux crossing the wall and cause too large numerical dissipation if flux vector splitting is used. To remove such errors, an appropriate treatment of wall boundary conditions is suggested. Inviscid and viscous steady transonic internal flows are analysed, including the case of shock-induced boundary layer separation.

Development of FEC and ESC performance characteristics for IDR carriers greater than 10 Mb/s

The requirement for restoration of high capacity fibre optic cables and the new tariffs approved for INTELSAT digital services has created a requirement to develop performance characteristics for IDR carriers greater than 10 Mb/s. This paper presents the trade-offs used in this development, and estimates the coding gains needed to meet these requirements. A number of FEC schemes are evaluated and a rate 3/4 convolutional code with soft decision Viterbi decoding is selected. Engineering service circuits (ESC) performance characteristics for IDR carriers greater than 10 Mb/s are also presented.

Pseudo-spectral Approximations for a Class of the Kdv-Burgers Type Equation

In this paper, the pseudo-spectral approximations for a class of the Kdv-Burgers type equation is presented. Convergence and stability of the approximation have been proved by Sobolev‘s inequalities and the bounded extensive method of the nonlinear function. Finally, the numerical examples are proposed.
