What is the influence of an upstream-mounted wing on the aerodynamic characteristics of a wheel and vice versa? How does the aerodynamic interaction between these components of the configuration depend on vertical, streamwise and spanwise position variations of the wing relative to the wheel? Which flow mechanisms and phenomena cause the observed behaviour and what would be the main factors of influence for these physics? Would it be possible to reproduce the qualitative (flow features and phenomena) and quantitative (correlation with experimental results) aspects of wing-wheel interaction with the use of current, 'state-of-the-art' CFD simulations?
