Computational fluid dynamics

Partly due to the rapid increase in computer power, speed and performance, computational fluid dynamics (CFD) plays an increasingly important role in the predesign as well as design stages of aircraft development by lowering costs and providing information on critical flow processes.

This project was an initial contribution towards validating advanced modelling methods for a broad range of aerodynamic flows directly relevant to civil aviation. Particular emphasis was put on the performance of turbulence models for maximum lift and high lift, single element aerofoils and multielement aerofoils and on shock boundary layer interaction in transonic conditions over aerofoils and bumps in channels as well as over wings. Other areas focussed on boundary layer schemes, tunnel interference effects, vortical flows including vortex breakdown and problems which arise when extrapolating wind tunnel data to free flight conditions.

It has provided new insight into CFD capabilities and has delivered important guidelines on which computational approaches are promising in several application areas.
