The Dawes and Denton codes, as they became known are now used worldwide
as an industry standard in the turbomachinery industry. The Dawes code
is now being developed for much wider usage. To handle real industrial
geometries, considerable attention has also been paid to automating the
link between computer aided design (CAD) and CFD via a suite of mesh generating,
editing and repair techniques being developed within the CFD Laboratory.
As Dr Mark Savill (CFD Lab manager) explains: "You have
to have an understanding of the system you are dealing with to use these
kinds of tools, to know whether the answer you have got is sensible or
not. That is where the combined expertise of all those involved in the
CFD Lab is invaluable. The software that we use is a tool that was developed
here, so we know intimately how it works and we have full control of the
source code, which is vital when we are pushing the boundaries with our
research. Not only that, we have access to experts in the fields of fluid
flow, combustion, dispersion and noise who understand the physics of the
processes we are dealing with and can therefore provide a sensible analysis
of the program outputs. Another key advantage of our general engineering
Department is that we can also call on expertise such as heat transfer,
petroleum engineering and bio and electrical mechanics and so readily
develop interdisciplinary project work."
