S & C Thermofluids has a wealth of experience in the application of computer aided design to fluid flow and heat transfer engineering. The main technique which the company applies is computational fluid dynamics (CFD), supplemented with 3D computer aided design (CAD).    Two general purpose CFD codes are applied by the company. These are FLUENT and PHOENICS.

The following capabilities of CFD have been utilised within S&C's work:

The CAD packages used by the company (CAD) can be used import geometry from elsewhere and to create surfaces of the topology that can readily be used to create a CFD mesh

To bolster the pre- and post-processing activities for all its analysis codes, S & C uses the FEMSYS engineering software. In particular, the software is coupled to S & C Thermofluids' infrared prediction software - FEMVIEW IR which allows the thermal energy emitted by an object to be predicted.

The company uses highly developed interface software - Phirefly (by Fluxion Ltd) to transfer CAD and analysis data across a range of formats (for example, FLUENT, PATRAN, Parasolid, PHOENICS).

Typical applications of S & C's analysis capabilities have included:

• Chemically reacting exhaust gas models
• Thermocouple transient response analyses
• Explosion models
• Catalytic converter models with light-off
• Flows within and around buildings
• Aircraft, missile and helicopter heat transfer models
• Processes involving non-Newtonian fluids
• Nuclear power plant safety
• Cylinder head cooling

For most CFD analysis, experimental validation and verification is strongly recommended.
S & C Thermofluids provides such validation through a number of its experimental facilities.
