    An Explicit Finite-Difference Scheme for Simulation of Moving Particles Abstract We present an explicit finite-difference scheme for direct simulation of the motion of solid particles in a fluid. The method is based on a second order MacCormack finite-difference solver for the flow, and Newton’s equations for the particles. Zero CKM mixing is excluded and mixing of order θ{sub Cabbibo} is allowed. Upper and lower limits on CKM mixing are exhibited as a function of m{sub H}. We use the default inputs of the Electroweak Working Group and also explore the sensitivity of both the three and four family fits to alternative inputs.

Building on this previous work, a new high-accuracy MacCormack-type scheme has been developed for use in computational aeroacoustics. 19 This scheme has been successfully applied to the real-world problem of supersonic jet noise prediction.

2° In this paper, the performance of this scheme will be evaluated using the benchmark problems of the fh'st. Recently, much progress has been made in improving the wave propagation qualities of MacCormack-type schemes. In this work, the linear wave propagation characteristics of MacCormack-type schemes are compared using several of the CAA Benchmark by: In addition to these schemes, the high-accuracy MacCormack-type scheme of Hixon will be used.

This scheme utilizes the Dispersion Relation Preserving methodology of TamAuthor: Ray Hixon. Due to their inherent dissipation and stability, the MacCormack scheme and its variants have been widely used in the computation of unsteady flow and acoustic problems. However, these schemes require many points per wavelength in order to propagate waves with a reasonable amount of : R.

Hixon. In this work, the MacCormack methodology is extended to implicit compact differencing schemes. A prefactorization method is developed which splits the implicit matrix into two independent upper and lower matrices which are easier to invert.

Using this method, a new class of high-order accurate compact MacCormack-type schemes is by: Evaluation of a high-accuracy MacCormack type scheme using benchmark problems [microform] / R.

Ohio: Institute for Computational Mechanics in Propulsion. Hoffmann, K. A., & Chiang, S. Through many numerical test problems, it is shown that the use of GODRP schemes can broaden the application area of conventional DRP schemes to aeroacoustic phenomena, enhancing both the speed and accuracy of the computation using nonuniform Cartesian or curvilinear by: Applying compact MacCormack type schemes with high accuracy approach, governing equations are solved using one-sided implicit stencil with five-point explicit boundary stencil.

Using MacCormack-type methods, a new class of highly accurate compact MacCormack-type schemes is derived which does not require a tridiagonal matrix inversion to obtain the spatial derivatives.

A new type of prefactored compact schemes is presented that obtains high-order accuracy while using a very small stencil size.

These schemes require fewer boundary stencils and offer simpler boundary condition implementation than the existing compact schemes.
