CFMS demonstrating the use of Computational Fluid Dynamics to predict flow on various objects

Fluids like air and water are all around us, but predicting the way they will flow is still very difficult. Modelling fluid flow using computers is known as CFD (Computational Fluid Dynamics).

This video shows CFD results for various flows which are especially difficult to model. Some of these flows are difficult to model because they require extra equations (e.g. the location of the water surface for the fish pass), while some are difficult to model because of how fast the flow is. Many of these flows are unsteady or turbulent, which is especially difficult for CFD because it makes the simulations very expensive, and can make it difficult to get the simulations to converge on the right answer.
