CFD simulation of deflagration–detonation processes using vector- and parallel computing systems

Implicit Schemes and Parallel Computing in Unstructured Grid Cfd

The development of implicit schemes for obtaining steady state solutions to the Euler and Navier-Stokes equations on unstructured grids is outlined. Applications are presented that compare the convergence characteristics of various implicit methods. Next, the development of explicit and implicit schemes to compute unsteady flows on unstructured grids is discussed. Next, the issues involved in p...

Large-scale Molecular Dynamics Simulation Using Vector and Parallel Computers

Distributed Parallel Computing Using Windows Desktop Systems

Like many large institutions, Indiana University has thousands of desktop computers devoted primarily to running office productivity applications on the Windows operating system, tasks which are necessary but that do not use the computers’ full capacity. This is a resource worth pursuing. However, the individual desktop systems do not offer enough processing power for a long enough period of ti...

Air shower simulation using geant4 and commodity parallel computing

The steeply falling end of the cosmic ray spectrum now extends up to ≈ 3 × 10 eV (see Ref. [1] for a recent survey), three orders of magnitude higher than the highest energy achieved by hadron colliders. Direct measurements using sophisticated equipment on satellites or high altitude balloons are limited in detector area and in exposure time. Ground-based detectors with large apertures make suc...

Hydrodynamics of Sieve Tray Distillation Column Using CFD Simulation

Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...
