Summary on Grant Application Form |
|
UMIST possesses a versatile CFD code, STREAM, which is used for turbulence modelling in aero-mechanical engineering. This project seeks to extend its capabilities in external aerodynamics and internal flows to civil-engineering applications such as wave loading on off-shore structures.To compute flows with moving boundaries - for example, engine flows or wave motion - it is desirable to solve flow equations discretised on a moving mesh. This is particularly attractive in finite-volume formulation, because the underlying conservation laws area readily expressed as integral equations over moving control volumes. In waves, however, the free-surface movement must be computed as part of the solution and a surface-conforming mesh continually regenerated. It is a non-trivial exercise to do so in a way which is, numerically, both accurate and stable.The utility of the exercise will be demonstrated by applying the code to test cases of immediate civil-engineering interest: submerged bodies (eg pipelines), junction flows (eg bridge piers) and gloating bodies (towing applications). These code developments are seen as a necessary first step in a more ambitious programme of work including computations of wave slam and harbour configurations.
