چکیده

In the present paper, we report high-fidelity CFD simulation of plume dynamics of a pulse detonation engine (PDE) by using modern parallel computer architecture. The two-dimensional axisymmetric Euler equations for reacting flows are solved by the Space-Time CESE method. A one-step global reaction is employed to model chemical reactions of a propane/air mixture. Computational domain includes the interior of the detonation tube and the aft quadrants of the PDE up to 12 feet in the axial direction and 4.5 feet in the radial direction. Numerical results of averaged pressures oscillation and the wave speeds compare well with the experimental data. For the required numerical resolution, we used a Beowulf cluster with the channel bonding. Our experience in using the system is summarized in the present paper.

Beowulf Cluster Design for Scientific PDE Models

This paper details some of the basic issues that arise when designing a Beowulf cluster for particular types of scientific simulations. The general problems of interest are partial differential equations (PDEs). These equations describe natural phenomenon and can be numerically solved. Finite differencing is used to solve the system of equations. This method naturally delineates the problem int...

Generation of nanoparticles by laser ablation: Combined MD- DSMC computational study

The early stage of the ablation plume formation and the following dynamics of the plume expansion are studied numerically using a combination of molecular dynamics and the direct simulation Monte Carlo methods. The direct cluster ejection from the target and the following cluster-monomer and cluster-cluster collisions are considered. The presence of the ablated clusters is shown to strongly aff...

Modeling of the Hydrocracking Reactor by the CESE Method

In this article, the improved space-time conservation element and solution element (CESE) method are used to simulate the dynamic treatment of the hydrocracking reactor. The dynamic model consists of four lumps: vacuum gas oil (VGO), middle distillate, naphtha, and gas which is dissolved by this method. The offered method can solve the partial differential equations caused by the reactions insi...
