Abstract

A three dimensional finite volume, unstructured mesh method for dynamic fluid-structure interation is described. The broad approach is conventional in that the fluid and structure are solved sequentially. The pressure and viscous stresses from the flow algorithm provide load conditions for the solid algorithm, whilst at the fluid structure interface the deformed structure provides boundary condition from the structure to the fluid. The structure algorithm also provides the necessary mesh adaptation for the flow field, the effect of which is accounted for in the flow algorithm. The procedures described in this work have several novel features, namely:

* a single mesh covering the entire domain.
* a Navier Stokes flow.
* a single FV-UM discretisation approach for both the flow and solid mechanics procedures.
* an implicit predictor-corrector version of the Newmark algorithm.
* a single code embedding the whole strategy.

The procedure is illustrated for a three dimensional loaded cantilever in fluid flow.
