The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach ... drag reduction, lift enhancement and flow-induced noise suppression. By controlling the flow, the fuel ... skin-friction drag for a laminar ... Center for Turbulence Research Annual Research Briefs 2010 ... Skin-friction drag reduction has significant practical value for marine vehicles. It is known that skin-friction drag accounts for more than 60% of the total drag of a cargo ship. For several decades, various methods have been explored to reduce the skin-friction drag. Polymer/riblet combination for hydrodynamic skin friction ...

In that study, the flow characteristics and flow distribution patterns of a single slot jet as well as a multiple slot jet located at the upper wall of a two-dimensional channel were analyzed numerically. The pressure distribution of the channel and the variation in skin friction coefficients along the impingement surface plate were also presented.

Reducing Friction. There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
