This data concern the publication: "Updating of Aerodynamic Reduced Order Models Generated using Computational Fluids Dynamics" by L.Griffiths, A. Gaitonde and D. Jones The data folder contains 19 folders (named Figure1 to Figure19), one associated with each figure in the paper. The data is available through eps files. The eps file can be read using a text editor and the eps file viewed using any eps viewer. Figure 1 is also provided as a pdf that can be viewed using any pdf viewer. The folder Figure1 contains data used to draw an information figure about discrete steps. The folders Figure2 and 3 contain mesh data with x and y non-dimensionalised by aerofoil chord. The folder Figure4 contains variation of force coefficients against mesh refinement factor. The folder Figure5 contains variation of force coefficients against non-dimensional tunnel length. The folder Figure6 contains pressure coefficient data against non-dimensional aerofoil chord position. The folders Figure7, 8, 15 and 16 contain change in force coefficents data against non-dimensional time. The folders Figure9, 10, 17 and 18 contain force coefficent phase angle data against reduced frequency. The folders Figure11, 12, 13, 14 and 19 contain change in force coefficents data against incidence.
