Computational Fluid Dynamics (CFD)

With the ever increasing need to enhance the commercial viability of complex industrial projects, the requirement to optimise capital expenditures on process improvements has become of paramount importance. Backed by MES’ expertise in Technical Safety, Risk Management and Asset Integrity, CFD forms part of a fully integrated package of services that can provide vital insight into industrial processes and operations, helping to make suitable decisions to boost business performance.

What is Computational Fluid Dynamics?

Blast wave propagation following vapour cloud explosion on a large offshore platform Blast wave propagation following vapour cloud explosion on a large offshore platform Computational Fluid Dynamics (CFD) is a powerful numerical tool that solves complex three-dimensional problems faced by the Oil and Gas Industry, involving fluid dynamics, multiphase flow, conjugate heat transfer, combustion, radiation and any other physical processes. As a result of the continuous improvement in computer science, CFD has become an indispensable design instrument that can now meet commercial project schedules.

The best available hardware and well-established CFD software packages (such as ANSYS CFD, Star-CCM+, KFX, FLACS) are used to provide accurate and rapid design solutions.

How can CFD help your business?

Key CFD applications offered by MES include:

  • Rigorous consequence modelling of major accident hazards, flare, controlled venting and exhaust;
  • Flow assurance studies to ensure reliable, efficient and safe transport of produced fluids;
  • Process analyses for troubleshooting and design verification.
