Plenary Sessions

Today's propulsion and power industry is in the middle of a Digitalization Journey which requires large investments and cultural changes to achieve challenging goals. Digitalization promises significant improvements in workforce efficiency, increase pace in design, manufacture and test, but also interconnectivity driven by more compute power, modern IT hardware and faster digital networks. A significant contributor to the Digitalization Journey is data.

A vast amount of data exist in organisations which needs to be better managed and utilized in order to support data-driven decisions and to create a data-centric culture. Challenges arise in a multitude of areas, belonging to data gathering, storing, handling and interpretating.

With invited speakers from cross-industrial organisations, this plenary session will explore and discuss the utilization and management of data in organisations and the application of modern data analytics and data science techniques to help with the Digitalization Journey in the Propulsion and Power community.

Bill Dawes

Professor Bill Dawes, Founding Director, CTO and Chairman, Cambridge Flow Solutions Ltd
Bill Dawes is the Francis Mond Professor of Aeronautical Engineering at Cambridge University. After completing a PhD at Cambridge he worked for the UK’s Central Electricity Generating Board where he developed and applied early computer-based flow simulation methods to steam turbine operational problems. Returning to Cambridge in 1984 he continued to work on a range of numerical methods – by now called CFD - aimed at predicting fully 3D viscous flow in turbomachines. His blade-to-blade RANS code (BT0B3d) became an industry standard design tool and was licenced to over 50 companies & organisations around the world. He then broadened the application base beyond blading to shroud flows, secondary air systems and blade cooling and then on to geometry itself as a research theme. For the last 20 years his research has drawn inspiration from advanced computer graphics and physics-based animation and attempted to enable seamless and tactile integration between solid modelling, mesh generation, geometry editing and flow simulation. The resulting software & environment, BOXER, is being developed by Cambridge Flow Solutions Ltd (of which Bill is a Founding Director, CTO and Chairman). Bill is a Fellow of the Royal Academy of Engineering and of the Royal Aeronautical Society and is a Chartered Engineer.
