Fluid Structure Interaction II by Hans-Joachim Bungartz download in pdf, ePub, iPad

You may need to model both the Navier-Stokes equations for fluid flow as well as the solid mechanics equations for the deformation of a solid body. However, stability of the coupling method needs to be taken into consideration. In conclusion, the partitioned approach allows reusing existing software which is an attractive advantage. Failing to consider the effects of oscillatory interactions can be catastrophic, especially in structures comprising materials susceptible to fatigue. It may even be possible to simplify the modeling of the flow as a thin film to model lubricating films.

On the other hand, development of stable and accurate coupling algorithm is required in partitioned simulations. The two classifications are the conforming mesh methods and the non-conforming mesh methods.

The two classifications are the

When modeling such systems, there are a variety of appropriate modeling approaches available. The solid structures can even be treated as entirely stationary obstructions in the fluid flow, with an objective of computing the stresses in the solid materials. The Navier-Stokes equations can be solved in various forms for different flow regimes. Industrial mixers, on the other hand, have moving parts, but the stirrers can be considered essentially rigid parts that agitate a fluid.

On the other hand development
