AEA Technology's CFX-4.4 is bubbling with potential
AEA Technology Engineering Software has announced major enhancements to its Computational Fluid Dynamics (CFD) modelling capability for process and chemical engineers, with the release of CFX-4.4. The software allows the highly complex fluid dynamic, heat transfer and chemical processes that occur in mixing vessels to be predicted accurately and efficiently.
CFX-4, fluid engineering software, is already established as the leading CFD software in the chemical and process industries for complex multiphase calculations. Version CFX-4.4 incorporates new features offering major benefits to the user. For example, CFX-4.4 has been modified to use Patran 9.5, giving access to later CAD package releases and has an easy to use look and feel. A new multiple frames of reference capability is included, providing the facility to define different frames of reference for different parts of the grid, whether stationary or rotating. The new feature provides a quicker and more efficient method of simulating rotor/stator interactions, for example, mixing vessel calculations in the process and pharmaceuticals industries, where the impeller is in a rotating frame and baffles are in a fixed frame.
Other valuable enhancements include a new free-surface modelling tool that tracks accurately the gas/liquid interface through grid movement. For combustion applications, a multi-grey gas capability has been included, allowing more accurate calculation of radiative heat transfer in furnaces. Parallel operation is now available on all hardware platforms, including homogeneous networks of any individual platform. This provides the most powerful method for solving large-scale CFD problems. CFX-4.4 enables easy simulation of real industrial flow processes, from settling tank sedimentation to bubbly flow in mixing vessels, and from jet flame impingement to coal-fired combustion plant.
About AEA Technology Engineering Software AEA Technology is a leading engineering software and consulting company. We develop and license the CFX software for fluid flow analysis, and offer consulting services, perform application projects and participate in development and research projects funded by either industrial clients or public institutions. We give our customers a competitive edge by helping them adapt and exploit technology so they can optimise plant and processes, enhance products, meet safety requirements and manage environmental challenges. CFX is a CAD-oriented Computational Fluid Dynamics tool for fluid flow analysis and design optimisation. The CFX software is well known for its excellent performance on parallel computer platforms running on Unix, NT and Linux. Built into CFX are some very powerful tools and efficient features, such as native CAD interfaces to read geometries directly from CAD systems without loss of information, a generalised grid interface to connect completely dissimilar, non-matching grids, regardless of how they were created, and multiple frames of reference to efficiently model flows with rotor/stator interactions. CFX has a unique coupled, algebraic multi-grid solver that provides best-in-class robustness and reliability. It includes facilities such as radiation modelling, advanced models for chemical reactions and multiphase flows, reacting particle tracking, fire simulation and special fluid analyses for wet steam and refrigerants. CFX clients are supported globally by more than 170 qualified and experienced staff members.
