This new technology intelligently sizes incompressible flow piping and ducting systems resulting in significant cost savings.

Cost Reduction Through Intelligent System Sizing

Traditional engineering methods are limited in their ability to select pipes, ducts and equipment sizes on a system basis. Even simple systems will have billions of potential size combinations to consider for their various components, far too many to evaluate by traditional methods.
With AFT Mercury, design requirements and sizing criteria are specified, which may be to minimise initial or life cycle cost, or parameters such as pipe weight, volume or surface area. AFT Mercury then performs a comprehensive analysis of the complex interaction among the various components to intelligently determine their optimal sizes.
Engineering optimizations will determine optimal pipe sizes to minimize one of the following as selected by the user:

• Pipe weight
• Pipe plus fluid weight
• Pipe volume
• Pipe surface area

Cost optimizations will determine optimal pipe and component sizes to minimize:

• Initial, or non-recurring costs (materials, installation), or
• Life cycle cost, the sum of non-recurring and recurring costs (energy, maintenance)

Leading Edge Pipe Flow Technology

Built on the advanced fluid flow analysis and system modelling capabilities of AFT Fathom, AFT Mercury can simulate your piping system in complete detail. Employing a robust solver to solve the governing equations of pipe flow calculations, AFT Mercury addresses open and closed loop systems, pump and control valve modelling, heat transferring pipes and heat exchangers.
