Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics (CFD) is a software tool for the prediction and analysis of complex fluid flows. The CFD method involves numerical solution of the fundamental equations that describe fluid-flow and heat transfer. The flow domain is modelled as a mesh, or grid, of many discrete volumes, enabling the analysis of complicated engineering geometries.

Until recently the complexity of CFD largely confined it to research programmes. However, advances in modelling techniques and computer hardware have dramatically reduced solution times, fuelling a significant growth in CFD use over many engineering sectors.

At Design Paradigm we have integrated CFD with our FEA and Engineering Design tools to ensure a significant impact on optimisation and problem solving processes.

Benefits include:

• Reduced test and prototyping requirements
• Flow investigation is not limited by test instrumentation
• Improved understanding of flow phenomena
• Fluid systems that are difficult to measure are readily modelled
• Improved product performance

CFD applications span a wide range of fluid systems including:

• Turbomachinery (e.g. compressors, turbines, rotor-stator systems)
• External flows (e.g. flow over vehicles, trains, buildings)
• Internal flows (e.g. ducting, exhaust systems, cooling, heat exchangers, ventilation)
• Pumps & fans (e.g. axial, radial, mixed flow)

Reasons to outsource your CFD requirement might include the following: insufficient resources, lack of in-house expertise, high workloads and being unable to justify the initial investment.
