Computational Fluid Dynamics (CFD) is the science of using computers to solve the governing equation of fluid flow and predict the behaviour of complex fluid systems.
With advances in numerical methods and computing power available, CFD has emerged as a valuable tool for the analysis of complex fluid systems. CFD methods offer a virtual test bed in which there are relatively fewer restrictions on number and location of solution points, allowing a more complete understanding of the fluid flow at a lower cost. Using CFD simulations, successive design optimisation iterations can be carried out early on in the conceptual design stage, eliminating the need for expensive design changes later on in the design process. In addition, as only a limited range of physical testing is required to validate the CFD model, the overall product development cost may be reduced.
CFD therefore has the power to deliver safer and more efficient designs at a lower cost.
Structures or assemblies exposed to fluid flow experience transient forces caused by fluid-structure interaction. Fluid forces spectra depends on different effects going from high frequency turbulence vibration in the acoustic range to larger excitations originated by recirculating unsteady flow. Obtaining pressure fluctuations conditions and evaluating the potential resonance response of the structure can help to avoid failure.
A number of industrial systems, such as hydrocarbon production systems, are exposed to erosion degradation over the design life which can result in component failure or reduced performance. Recent advances in CFD modelling of particle transport together with experimental correlations for erosion have made the numerical simulation of erosion for complex components a reality.
Separation of liquid-liquid and liquid-gas mixtures is a central design challenge in the Processing industry. Computational fluid dynamics (CFD) simulations of the behaviour of these complex fluid interactions can give valuable insights into design performance across a range of operating flow conditions and challenging environments such as on-board vessel separation in extreme storm conditions. These insights into the fluid dynamics of the problem are valuable to design and operation decisions, helping operators save money and operate their systems safely and continuously.
Aerodynamic forces can play a vital role in many engineering applications. I.E wind power industry facing new challenges offering innovative designs is supported by the use of computational fluid dynamics. SDEA collaborate actively in the design stage of the rotor blades to get the optimal throughput for every environmental condition.
