What is Computational Fluid Dynamics (CFD)?

Computational Fluid Dynamics is a powerful engineering tool for simulating all types of fluid flows. CFD simulations produce detailed descriptions of flow characteristics including values for velocities, pressures, and other variables. Thermal characteristics and other advanced physics, like chemical reactions, can also be simulated.

Why Use CFD?

CFD significantly reduces design and development time, provides detailed information otherwise not available from physical experiments, and quickly simulates a wide range of flow conditions. The results are improved designs, lower risk, and shorter time to market for a product or process.

How does it work?

CFD simulations involve solving numerically the fundamental laws of physics, called governing equations, which mathematically describe the properties and motion of fluids. The CFD modeling process occurs in three fundamental steps:
