Abstract
The numerical results on turbulent crossflow past a circular 2-D cylinder are presented. The cylinder has inner ducts used to bypass some amount of the oncoming flow from forward stagnation point to the rear cylinder part. The influence of the angle position of bleeding jets and the bypass flow rate on the cylinder drag coefficient and lift force amplitude as well as their fluctuations are investigated. By the ventilation the drag coefficient reduces up to 47%, the lift force amplitude decreases more than in 5 times and Strouhal number increases around 30% in average. The angle coordinates at which bleeding configuration of two jets has some advantage about the one central jet has been determined.
