Statistical data

In this section the relevant statistical data for the flow around the wing-body junction computed with MIGALE is given. The reported data is the one mentioned in Table 1 of the list of desirable quantities (PDF). The data is available as .vtu (ASCII) format.

Volume data

Volumetric data of the statistics are provided here. For more information regarding the stored quantities and the storage format, please refer to the storage format guidelines.

The available files are:

Surface data

Surface data of the statistics are provided here. For more information regarding the stored quantities and the storage format, please refer to the storage format guidelines.

The available files are:

Profile data

Profile data have been extracted from the symmetry plane $z/T=0$ at different streamwise locations ( $x/T=-0.45,-0.40,-0.35,-0.30,-0.25,-0.20,-0.15,-0.10,-0.05,-0.01$ ) and made dimensionless with respect to reference quantities ( $u_{ref}$ , $\rho _{ref}$ ). The data stored in each file are:

vertical location $y/T$
average velocity components $U_{i}/u_{ref}$
Reynolds stress components $R_{ij}/(\rho _{ref}u_{ref}^{2})$
turbulent kinetic energy $k/u_{ref}^{2}$

Profiles at selected streamwise locations are reported in Fig. 13.

Contour data

Contour data of the averaged velocity components $U$ and $V$ , the three normal stresses $R_{xx}$ , $R_{yy}$ and $R_{zz}$ , the turbulent kinetic energy $k$ , and the shear stress $R_{xy}$ in the symmetry plane are provided in Fig. 14. As the region depicted is in front of the leading edge, it is visible the effect of the horse-shoe vortex: while the streamwise component of the velocity becomes negative above the horizontal solid wall, the normalwise one presents a large negative region close to the leading edge. This results in a clockwise rotating vortex. Within this vortex the Reynolds stresses as well as the turbulent kinetic energy show the maximum intensity. Moreover, looking more in detail, it is possible to notice the presence of a tiny vortex in anticlockwise rotation clinging to the leading edge of the wing, near the wing-body junction.

All contours are normalized with respect to the reference quantities.
