Item type:Publication, Access status: with files , A computational study for flow past a junction with a strake(2019-09); A strake is a practice device to install in front of a wing-body junction to suppress horseshoe vortex. In this paper, we designed a strake for a finite wing mounted on a flat plate. Its profile on the plane of symmetry is an ellipse. The horizontal cross sections of the strake are also elliptical. The flow due to a flat plate boundary layer passing the wing with zero angle of attack was studied computationally. Some sets of values of the strake length and height were chosen for study. The flow was first studied computational via RANS equations. The solutions which show no horseshoe vortex were then picked. Then the LES computations were employed to investigate the detailed flow characteristics. The solution by RANS computations represents the time-averaged one and that by LES computations depicts the instantaneous features of the flow. Some interesting features not revealed in RANS computations were found in LES computations.Publicationtype: Conference Paper78 228
