Advitech is highly experienced in many aspects of risk management and functional safety.

Our proven methodologies and rigorous approach can be applied to any risk context to achieve safety of people, operations, the environment and the community.

We work within the framework of international and other relevant standards for Risk Management, Process Risk and WHS regulations.

Our customers benefit from our experience, which enables us to suggest relevant and effective controls to reduce risk levels to as low as reasonably practicable (ALARP).

Computational Fluid Dynamics (CFD)

Building on our strong reputation across a number of industry sectors for our Hazardous Areas Classification (HAC) services, Advitech also offers Computational Fluid Dynamics (CFD) Modelling & Simulation, taking HAC to the next level. CFD can add substantial value over HAC alone (including the real potential for significant long-term cost benefits) for those working within an industry where process specific zoning applies.

Our CFD modelling and simulation capability is the result of a service partnership arrangement with global engineering services firm and CFD modelling specialists, Jimmy Lea & Chartered Engineers.

What is CFD?

In simple terms, Computation Fluid Dynamics (CFD) is a recognised type of engineering calculation that allows a more detailed review of the probable extent of potential hazardous zones, producing more refined (potentially smaller or fewer) zone areas, thereby reducing the need for protected electrical equipment. CFD is the science of predicting fluid flow, heat and mass transfer, chemical reactions and related phenomena by solving the mathematical equations which govern these processes. The numerical process utilised depends on the modelling techniques adopted – such as Single Phase, Multiphase or Turbulence modelling.

What are the benefits of CFD?

A classified hazardous area establishes a legal requirement for the site owner to acquire suitable electrically protected equipment for the defined area. This can represent a significant capital outlay and ongoing maintenance costs. CFD can:

  • Be used to visually show the outputs of a HAC compliant result
  • Help justify smaller hazardous area zones where electrically protected equipment is required
  • Reduce the initial capital cost of electrical equipment (as fewer ‘protected’ items may be required)
  • Reduce the overall life cycle cost as there is less equipment that is subject to a strict maintenance and inspection regime
  • Significantly also, the results of a well-prepared CFD model could, in certain situations, be regarded as a suitable tool for use by an expert witness in a legal context

Do I need CFD or HAC?

Advitech’s process engineers have the skills to identify when standard HAC one-dimensional calculations on their own are insufficient for your specific situation. The needs analysis process includes a detailed cost benefit analysis to ensure an investment in CFD modelling would be worthwhile. Advitech’s process engineers provide Jimmy Lea’s CFD consultants with all the detailed information they need to prepare appropriate CFD models. CFD models and output results are interpreted by Advitech's engineers, as we have the in-depth understanding of your organisation and its specific needs.
