Computational Fluid Dynamics (CFD) engineering relies on advanced computing technology to simulate the complex behavior and interaction of liquids and gases. It is a valuable engineering tool used in the design, evaluation and optimization of fluid flow processes.

AECOM Process Technologies has an extensive, in-house CFD engineering team providing services to multiple industries. We have 20 years of experience using CFD simulation as an engineering design tool to guide and support the development, evaluation, and optimization of chemical and physical processes. The combination of our extensive industry experience and our world-class CFD capability distinguishes us from other firms. We use state-of-the-art CFD software and operate a dedicated in-house parallel server cluster to provide high-resolution engineering simulations. Our advanced CFD hardware permits superior computational mesh resolution and the ability to evaluate complex heat and mass transfer processes.
