Akpan, On a High-Order Compact Scheme and Its Utilization in Parallel Solution of a Time-Dependent System on a Distributed Memory Processor, Network and Parallel Computing, /_1, (), ().   An efficient discrete singular convolution (DSC) method is introduced to the numerical solutions of incompressible Euler and Navier-Stokes equations with periodic boundary conditions. Two numerical tests of two-dimensional Navier-Stokes equations with periodic boundary conditions and Euler equations for doubly periodic shear layer flows are carried out by using the DSC method for spatial Cited by: 9.

    The flow in the distributor and the runner of the GAMM workshop water turbine has been predicted by numerical solutions of the incompressible Euler equations. The Euler solver uses the artificial compressibility technique in order to find a steady : Peter Eliasson. Search term. Advanced Search Citation Search. Search term.

    The numerical method for the cartesian coordinate system solves the equations in the form described in [10] and recalled in §2. We will illustrate in §3 the main properties of the scheme concerning spatial and temporal discretization, as well as the use of compact, high-order finite differences for . A two-dimensional nine-velocity lattice model is developed for the numerical simulation. Validation of the FDLBM is carried out against microchannel and microtube flows, a driven cavity flow, and a two-dimensional sudden expansion flow. Excellent agreement is obtained between numerical calculations and analytical solutions of these by:

Blech National Aeronautics and Space Administration Lewis. A new parallel numerical scheme for solving incompressible steady-state flows is presented. The algorithm uses a finite-difference approach to solving the Navier-Stokes equations. The algorithms are scalable and expandable. They may be used with only two processors or with as many processors as are available.

The code is general and expandable. Abstract. A parallel numerical method solves the solutions of the incompressible Navier-Stokes equations is developed.

The method uses a third-order upwind finite volume scheme to discretize the convective terms and second-order finite volume method to discretize the viscous terms.

For the unsteady solutions, the second-order Crank-Nicolson method is used for the time : San-Yih Lin, Zhong Xin Yu. High-order numerical methods provide an efficient approach to simulating many physical problems.

Deville, P. Fischer, E. Mund. The chapter demonstrates that the high order schemes allow for the efficient massively parallel implementation with no damage to the high accuracy of the computed CFD solution. It also presents the results of numerical experiments with the 3D Dow Chemical stirred tank reactor problem.

This chapter discusses the parallel algorithm for the numerical simulation of 3D incompressible flows. It describes the algorithm for numerical simulation of unsteady viscous incompressible flow in 3D rectangular computational domain.

The algorithm is implemented on the claster parallel computer system. MTS methods are virtually nonexistent for the incompressible Navier-Stokes equations because the solution is very sensitive to the pressure, which satisfies an elliptic Poisson problem at every.

The idea of predictor–corrector schemes is to remedy this by iterating within a time step the latter scheme to recover the monolithic solution. This is accomplished by substituting p n + 1 and p n by p n + 1, i + 1 and p n + 1, i in by: The present work is concerned with a study of numerical schemes for solving two-dimensional time-dependent incompressible free-surface fluid flow prob-lems.
