235 縦渦による流れの剥離制御 : 翼型特性の向上(G05-3 剥離制御・抵抗低減,G05 流体工学)  [in Japanese] 235 Control of Flow Separation by means of streamwise vortices : Improvement in Characteristics of an Aerofoil  [in Japanese]

Solid type vortex generators that are known to be effective on suppressing flow separation have been widely used in various fluid mechanical elements such as intakes and airfoils of airplanes, but it is not adaptable to flow field variation, that is it become just an obstacle to augment the drag in the situations when it does not work. In this study, wind tunnel tests have been carried out for a vertical blowing jet type vortex generator installed on an airfoil model to investigate the separation control capability. This study was investigated on the effects of configuration, location and blowing speed of the vortex generator to the lift and drag. As a result vortex generator was found to have a high capability in separation control.
