Subsonic flow in a corner
Abstract
Laminar and turbulent flow, as found e.g., at the wing-fuselage junction, were studied numerically. In laminar flow a vortical system close to the edge disturbs calculations. Modifications to the field of the secondary velocity improve this. Further improvement can be achieved by varying vortex parameters. In the turbulent mode, the anisotropy of the turbulence should be considered in the calculation of the second order vortices, (although here it was ignored, and qualitatively correct results are still obtained). The basic equations are the streamwise momentum equation, the streamwise component of the vorticity equation, and two Poisson-type equations for secondary velocities.
