WHAT IS CFD?

What is CFD?

Computational Fluid Dynamics (CFD) is a branch of mechanics that uses numerical analysis and data structures to analyse and solve problems that involve ‘fluid’ (liquids and gases) flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid with surfaces of different shapes and textures. The software is constantly evolving to improve the accuracy and speed of more and more complex simulation scenarios. Validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed analytical or empirical analysis of a particular problem can be used for comparison. A final validation is often performed using full-scale testing.

What is CFD used for?

CFD is applied to a wide range of research and engineering problems in many fields of study and industries, including aerodynamics and aerospace analysis, hypersonics, weather simulation, natural science and environmental engineering, industrial system design and analysis, biological engineering, fluid flows and heat transfer, engine and combustion analysis, and visual effects. At Woods Air Movement we use CFD to develop our products and to design ventilation systems in buildings, staircases, tunnels and parking garages.

Computational Fluid Dynamics (CFD) is a highly advanced technique and its importance is hard to overstate in the HVAC industry. By using CFD, our engineers can accurately predict fluid dynamics, such as pressure, temperature, velocity, and turbulence in complex systems or processes that would be impossible to study through traditional experimentation.

How can CFD help me?

Our CFD services are an indispensable tool, providing a detailed understanding of air flow in a wide range of situations, which can not only significantly benefit a company’s bottom line, it can also improve site safety. Analyzing where fumes or pollution could build up to hazardous levels or how hot smoke will behave in the event of a fire, will help you design and build the most effective ventilation system.

By simulating the airflow in and around structures, we can determine the most effective placement of fans, diffusers, and air handlers to ensure proper air distribution and minimize energy consumption. It can also be used to validate existing systems, highlighting areas where ventilation or smoke extraction may be inadequate. Using CFD simulations we can demonstrate how improvements to your systems can be made.
