What is Computational Fluid Dynamics?

CFD is the systematic application of computing systems and computational solution techniques to mathematical models formulated to describe and simulate fluid dynamic phenomena.

CFD is part of computational mechanics, which in turn is part of simulation techniques. Simulation is used by engineers and physicists to forecast or reconstruct the behaviour of an engineering product or physical situation under assumed or measured boundary conditions (geometry, initial states, loads, etc.). A variety of reasons can be cited for the increased importance simulation techniques have achieved in recent years:

  • Need to forecast performance
  • Cost and/or impossibility of experiments
  • The desire for increased insight
  • Advances in computer speed and memory (1:10 every 5 years)
  • Advances in solution algorithms

The simulation of flows is accomplished by:

  • Solving numerically partial differential equations (PDEs),
  • Following the interaction of a large numbers of particles, or
  • A combination of both.

CFD, by its very nature, encompasses a variety of disciplines, which may be enumerated in the following order of importance:

  • Engineering
  • Physics
  • Mathematics (classic and numerical analysis, discrete mathematics)
  • Computer Science (algorithms, coding, software)
  • Visualization Techniques
  • User Community (benchmarking, documentation, teaching)

Researchers Unveil New Blood Flow Simulation System

Researchers at George Mason University’s Center for Computational Fluid Dynamics recently unveiled a first of its kind patient-specific blood flow simulation system that was assembled by Phillips Medical Systems using software components developed at Mason. The cutting-edge technology has the potential to improve diagnostics and treatments for millions of Americans who are affected by brain aneurysms — saclike bulges in the blood vessels — each year. A multi-disciplinary team comprised of Mason’s computational scientists, Inova Fairfax Hospital’s neuroradiologists, and Phillips Medical System’s engineers, produced the application to provide neurologists with hemodynamic (blood flow) information that is believed to be of fundamental importance for understanding the evolution and rupture process of brain aneurysms.
