What is CFD?
Computational Fluid Dynamics is a methodology that allows engineers to predict the performance of their designs when exposed to fluid flow, either internal flow (such as the flow of air and gasoline through an engine manifold) or external flow (such as the aerodynamic flow past an automobile or the hydrodynamic flow past a boat). CFD software programs can simulate problems involving gases, liquids and solids and multi-phase problems that depend on the interaction of any number of the above. CFD is used in the design of almost every major product. Reducing uncertainty in the design process, and resulting in higher quality products and designs, with greater robustness that better meet customer requirements.
More than Flow!
Although most practical engineering problems involve fluid dynamics to some extent, finding the solution to real-world engineering challenges involves taking accurate account of a range of physical phenomena. For this reason CFD tools can account for wide range of associated physics, including heat transfer, chemical reaction, combustion, solid transport and acoustics. One important class of problems are those that involve FSI or Fluid Structure Interaction, where the fluid flow influences a physical structure - such as the bending of an airplane wing, or of a boat being slammed by waves. Computational Fluid Dynamics simulations can account for both the influence of the fluid on the structure, and of deformations in the structures shape on the fluid.
Simulate the System
Complex industrial problems require CFD solutions that span a multitude of physical phenomena, which often can only be solved using simulation techniques that cross several engineering disciplines. Engineers demand the ability to "see the big picture". Simulating whole systems with Computational Fluid Dynamics and not just individual components, taking account of all the factors that are likely to influence to performance of their product in its working life. In short, to simulate the performance of their design in the context that it will actually be used.
Multi-disciplinary Design Exploration
Although CFD is can usefully be applied to almost any engineering problem, it's real value comes from being able to improve a product or design through multiple design iterations, using engineering data from the simulation results to drive the design process. Ultimately this results in higher quality, robust products, that better fulfill customer expectations.
CD-adapco is pioneering an approach called "MDX" or "Multi-Disciplinary Design Exploration", in which sophisticated software is used to drive the simulation through a complete range of operating scenarios, including a range of geometrical configurations and different operating points. This approach can be used to gain a complete understanding of the performance of the product across the whole design space. When combined with HEEDS, CD-adapco's dedicated optimization software, the MDX approach can be used to calculate the best possible combination of design parameters to maximize the real-life performance of the product.
