The latest release of CFX-ProMixus software provides a cost-effective and time-saving tool for optimal design of chemical reactors.

Harwell, UK - February 1st, 2002 - CFX, part of AEA Technology, today announced a major upgrade to its chemical reactor design software tool, CFX-ProMixus.

CFX-ProMixus provides detailed analysis of mixing vessel processes through an embedded and fully automated computational fluid dynamics (CFD) solver. Using an intuitive interface, the user specifies reactor configurations from an extendable library of tank, baffle and impeller templates. CFX-ProMixus then automatically performs a CFD simulation of the flow within that vessel. The output is presented as a gallery of images and tables that permits pre-selection of component designs and reduces the number of iterations needed to develop optimum mixing performance.

"Major impeller manufacturers, including Chemineer, Cleveland Eastern, Lightnin and Philadelphia Mixers, are now supporting our software", said Michael Raw, CFX's VP of Product Development, "These companies have provided new templates of their industry-standard impellers which are readily accessible in our software, making CFX-ProMixus a virtual mixing vessel."

The new capabilities of CFX-ProMixus reinforce CFX's commitment to combine powerful analysis tools with user-friendly interfaces to create 'best-in-class' software. It adds many new impeller libraries, including new generic impellers (flat blade, pitched blade, retreat curve, curved blade and Smith turbine) and impellers from Philadelphia Mixers (high-solidity and low-shear hydrofoils), Chemineer, Cleveland Eastern Mixers and Lightnin (A310 and A320).

Also new is a collection of on-line examples showing how users can employ the software to solve more advanced mixing flows such as non-Newtonian rheologies, heat transfer in jacketed vessels, tanks with dip tubes and two-phase mixing (liquid/solid and liquid/gas).

CFX-ProMixus is now available for Silicon Graphics and Windows 2000 computer platforms in addition to Windows NT workstations.

"This new release reinforces our Mission Statement, which is to improve our customers' efficiency and profitability by delivering outstanding CFD solutions and support" added Chris Reid, CFX President.
