A new technology for reducing turbulent skin friction, called the Microblowing Technique (MBT), is presented. Results from proof-of-concept experiments show that this technology could potentially reduce turbulent skin friction by more than 50% of the skin friction of a solid flat plate for subsonic and supersonic flow conditions. Skin Friction Measurements using Oil Film Interferometry ... Skin Friction Measurements using Oil Film Interferometry and Laser Doppler Anemometry ... such as viscous drag reduction. Oil film interferometry (OFI) and laser Doppler anemometry (LDA) measurements have been carried out at several locations downstream of the wall jet exit. Velocity profiles from the LDA measurements have been analyzed using a NON-UNIFORM SLOT INJECTION (SUCTION) INTO WATER BOUNDARY ...

Piled foundations - University of the West of England, Bristol Piled foundations Adapted from the Foundation section of the GeotechniCAL Reference Manual Author: David Toll (Durham Univ.) Piles generally used because adequate bearing capacity can not be found at shallow enough depths to support the structural loads. It is important to understand that piles get support from both end bearing and skin friction. HOW TO Prepare A Manuscript FOR TSFP-5 Howard, F. G., Hefner, J. N. and Srokowski, A. J., 1975, 6(b).

An experimental study of skin friction reduction in a Mach 3.0 air steam with gaseous injection through a tangential slot, a porous wall section, and combinations of the two was conducted. The primary data obtained were wall shear values measured directly with a floating element balance and also inferred from Preston Tube measurements. Leading-edge slot - Wikipedia A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed.
