CFD Modelling

One of the tools to solve some of the toughest free-surface flow problems is computational fluid dynamics (CFD) modelling. FLOW-3D, our chosen modelling software, has been used worldwide for over 20 years. Nowadays, simulations have similar run times of two-dimensional models, and run  efficiently without the need for supercomputers. CFD assessments are based on a 3D model from day one, avoiding the need to convert the 3D structure to a 2D format. This avoids loss of design features, and allows for the streamlined provision of meaningful design input early in the design process. Our engineers have experience applying CFD modelling to support:

  • Bridge design and culvert optimisation;
  • Dam spillway design;
  • Pumped hydro design;
  • Weir design;
  • Fish passage design;
  • Water treatment plan performance assessments; and
  • Wastewater treatment plant optimisaiton.
