What is Computational Fluid Dynamics? |
The flow of fluids inside spaces of various geometry or around objects can be described by the so-called Navier-Stokes equations. These non-linear partial differential equations are derived from the notion that mass and momentum are conserved (or, actually, balanced) inside the fluid. The Navier-Stokes equations cannot be solved analytically for all but the simplest flow systems. However, with the spectacular increase in computation power of affordable PC's, it has now become possible to solve these equations numerically. The numerical technique to solver the flow equations, development of which started in the early '60s, is called Computational Fluid Dynamics.
The CFD codes that are on the market today are almost all very powerful and quite large software packages. This power enlarges the range of flow problems that can be computed and the accuracy with which the flow can be calculated. However, it also makes these software programs expensive and computation power-hungry. Also, due to the complexity of these codes, a lot of expertise is needed to obtain correct and accurate results. While, for many applications in high technology and science this kind of investment is justified, there is as wide range of applications for which CFD would be useful, but for which these heavy software packages are too expensive or knowledge-intensive. Which is where Comflow^{®} comes in.
