What is Computational Fluid Dynamics (CFD)

With advancements in micro-processor technology and the wide availability of powerful personal computers, complex flow problems can now be solved on the desktop.

Computational Fluid Dynamics (CFD)  is a phrase that refers to a family of computer methods used to solve the fundamental equations for fluid flow.

In a CFD simulation, the region of interest (the domain) is sub-divided into an interconnected lattice of small cells (control volumes). Within each individual cell the fluid flow equations are solved using information from its neighbouring cells.  Iterating from initial conditions, a computer is used to perform many millions of repetative operations and the result is a fluid flow simulation which replicates the performance of the prototype system.

In addition to the computation of fluid flow, CFD techniques can also be used to compute the dynamic behaviour of related processes including heat-transfer, solidification, sedimentation, and dispersion.

At CFD Solutions Ltd we utilise the latest generation of commercial CFD programs as well as our own in-house algorithms to solve the most challenging of fluid flow problems.
