Turbomachinery CFD on parallel computers

Turbomachinery CFD on Parallel Computers

The role of multistage turbomachinery simulation in the development of propulsion system models is discussed. Particularly, the need for simulations with higher fidelity and faster turnaround time is highlighted. It is shown how such fast simulations can be used in engineering-oriented environments. The use of parallel processing to achieve the required turnaround times is discussed. Current wo...

CFD for Turbomachinery Internal Air Systems

Considerable progress in development and application of CFD for aeroengine internal flow systems has been made in recent years. CFD is regularly used in industry for assessment of air systems, and the performance of CFD for basic axisymmetric rotor/rotor and stator/rotor disc cavities with radial throughflow is largely understood and documented. Incorporation of three dimensional (3D) geometric...

An Evaluation of Cost Effective Parallel Computers for CFD

An evaluation of the current status of two novel clusters, running Linux and NT, has been made to assess their performance for parallel CFD calculations. The core algorithm of the code is the conjugate gradient method used to solve the pressure equation. For good performance, a low latency and high bandwidth is required and the results indicate that, without substantial investment in this area,...

Parallel Cfd on Commodity Processors

In recent years, the cost of microprocessors for PCs has reduced dramatically. This has led to the introduction of a new class of computing facility commonly known as Beowulf systems, in which commodity-off-the-shelf PCs and networking components are combined into a single cost-effective parallel system. We report our experiences in implementing a number of CFD codes on a 32-processor Beowulf-c...
