摘要
By incorporating the Monotone Upwind Scheme of Conservation Law (MUSCL) scheme into the smoothed particles hydrodynamics (SPH) method and making use of an interparticle contact algorithm, we present a MUSCL-SPH scheme of second order for multifluid computations, which extends the Riemann-solved-based SPH method. The numerical tests demonstrate high accuracy and resolution of the scheme for both shocks, contact discontinuities, and rarefaction waves in the one-dimensional shock tube problem. For the two-dimensional cylindrical Noh and shock-bubble interaction problems, the MUSCL-SPH scheme can resolve shocks well.
