چکیده
The co-flow jet is a zero-net-mass-flux active flow control strategy and presents great potential to improve the aerodynamic efficiency of future fuel-efficient aircrafts. present work integrate technology into shape optimization further realize co-flow-jet airfoil performance. results show that maximum energy ratio lift augmentation drag reduction increased by 203.53% ( α = 0°) 10.25% 10°) at Power-1 condition (power coefficient 0.3), respectively. A larger curvature observed near leading edge optimized shape, which leads early onset separation improves transfer from free stream. In addition, higher mid-chord characterized accelerating in middle airfoil, increasing strength negative pressure zone, thus improving stall margin enhancing circulation.

متن کاملMixing Mechanism of a Discrete Co-Flow Jet Airfoil
The flow mechanism leading to the enhanced performance of a discrete co-flow jet (dCFJ) airfoil is investigated. Flow visualization and DPIV are used to analyze the difference between the flow along discrete jets and over the tabs used for discretization of the slot jet. Results show that the entrainment is uniform over the leading jet as long as the tab size is small enough. The jets expand sp...
