Computational fluid dynamics (CFD), studies the movements of a fluid, or its effects, by digitally resolving the equations that apply to fluids. It is a simple and efficient manner to highlight air diffusion or extraction problems, based on scenarios and new strategies.

Thanks to Computational Fluid Dynamics, we are able to:

  • Better understand aerolic and thermic effects
  • Simulate the airspeed and heat transfer
  • Analyse particle trajectories
  • Use modelling to facilitate conception, design or reorganisation of flows.
  • Determine the best air change rate in a room
  • Foresee air flows, even before having carried out measurements or modifications on HVAC installations
  • Optimise the final design of installations or predict the impact of modifications on ongoing constructions
  • Verify the influence of operators on air flows and master the deviations

Added value:

  • Easily understand and modify the air flow at lower cost before carrying out an actual optimisation
  • Reduce the lapse of time of the design process
  • Increase accuracy
  • Get good results on first try
  • Optimise energy consumption
  • The analysis of air flows makes risk analysis easier

In general, resolving a CFD problem needs three main steps:

•Preparation of the problem: this passes through a definition of geometry, a discretised mesh of the calculation domain.

>It is in this specific phase, where Imag’Ing proposes its added value, providing realistic and simplified 3D CAD models, based on laser scanning survey.

  • The digital resolution of the problem, which goes through the execution of specific software.
  • Exploitation of the results (verification of the original CFD coherence/problem).
