✦ Synopsis


The second-order extenmon of Godunov's method for hyperbohc conservatton laws, known as MUSCL schemes, is studied in thxs paper. We present a new type of Eulenan MUSCL scheme and oscillation-free algorithms The mtercell flux is computed from difference approximations of characteristic equations with the data influencing the values at half-time step The data for characteristm equations are classified m several different types by the domain of dependence The oscillation-free algorithm, based on TVD method, gives a general formulation for previously used method and promdes a class of limiters including exmtmg hmaters. To validate the new TVD-MUSCL scheme, numencai experiments are performed for several model problems m one and two dxmensions (~)

In this paper, we present a two-step, component-wise TVD scheme for nonlinear, hyperbolic conservation laws, which is obtained by combining the schemes of Mac Cormack and Warming-Beam. The scheme does not necessitate the characteristic decompositions of the usual TVD schemes. It employs component-wi

Many of the problems of approximating numerically solutions to nonhomogeneous hyperbolic conservation laws appear to arise from an inability to balance the source and flux terms at steady states. In this paper we present a technique based on the transformation of the nonhomogeneous problem to homoge
