What is CFD?

Computational Fluid Dynamics(CFD) is an advanced field of fluid mechanics that utilises numerical analysis and data structures to solve and analyse problems involving fluid flows. By harnessing the power of computing, we are able to simulate the interaction of liquids and gases with surfaces defined by boundary conditions and subject to various physical properties and forces.

Essentially, CFD is a virtual fluid dynamics lab, allowing for the modelling of fluid behaviour across a broad spectrum of applications. Using numerical models, we can predict the behaviour and dynamics of fluid motion. Doing so gives us a comprehensive look into performance and efficiency. It also enables us to provide valuable insights into current and proposed systems, identifying areas for further improvement.

How Computational Fluid Dynamics can help your projects

CFD plays a pivotal role across a wide range of industries as it enables analysis of fluid flow processes and heat transfer. This computer-based fluid simulation tool aids in the understanding and prediction of liquid movement and its interaction with surrounding structures.

There are several reasons why this practice is essential for business and safety operations, including:

  • CFD provides a predictive understanding of fluid behaviour in complex systems. This reduces risk and enable efficient designs the aerospace, automotive, and maritime engineering industries.

  • By employing CFD analysis, engineers actively refine designs to enhance performance. As a result, vehicles achieve greater aerodynamic efficiency, plants operate more reliably, and HVAC systems are engineered for energy efficiency.

  • By predicting how gases or liquids will behave under various conditions, CFD helps in assessing and mitigating potential risks such as toxic gas dispersion, development of explosive environments, overpressure events and failure of equipment.

  • Physical prototyping and testing can be prohibitively expensive and time-consuming. CFD reduces the reliance on experimental testing, thus cutting down the cost and time to market. There are also many situations where physical testing is not practical such as high pressure equipment or complex overpressure events.

  • CFD plays a pivotal role in environmental modelling. This practice ensures compliance with drinking water standards, allowing us to understand water quality, assess gas dispersion, optimise thermal comfort, analyse chlorine contact, and examine other wastewater treatment processes.
