Along the leading edge of the wing there is something called a stagnation line, which is the dividing line between air that flows over the top of the wing and air that flows under the bottom of the wing. On an airplane, the stagnation line runs the length of the wingspan, but since ...
The results are relevant to engineering applications where the air–water bubbly flow in a free-stream is important. Keywords: bubbly flows; two-phase flows; high-speed imaging; hydrofoil 1. Introduction The two-phase flow of air injection in water in engineering applications affects drag ...
(shown by Arrow A in FIG. 3) into the airflow sections24. The distal end20of the plug body16may have a substantially flat shape. When the damper blades26are fully open, the damper blades26complete the airfoil shape making the plug body16airfoil shaped on both the upstream and downstream...
This technique has been applied extensively around the leading edge and on both pressure and suction sides of an airfoil. Film injection at the leading edge of an airfoil affects flow and heat transfer characteristics over the entire airfoil. Film cooling effectiveness and heat transfer distributions...
A major challenge is to keep an airship more or less over the same spot on earth. Absent some means of propulsion, winds aloft would otherwise cause the airship to drift from its intended location. To maintain its station, the airship must constantly fly into the wind at wind velocity. ...

As air flows around the leading edge, it flows over the trapped vortex and is pulled in and down to generate the lift. There are two routes that can be seen from the graphs, the first route which is the positive angle transit to negative angle (Downstroke) and the second route is the...
