Submarines - Polymer Drag Reduction

Abstract Experiments were conducted to determine the reduction in surface skin friction and the effectiveness of surface cooling downstream of one to four successive flush slots injecting cold air at an angle of 10 deg into a turbulent Mach 6 boundary layer.

Abstract. The paper investigates analytically the effect of multiple slot injection on skin friction for a representative fuselage shape (ogive-cylinder body) and evaluates the potential of slot injection as a drag reduction system in subsonic flow. of Multiple Flush-Slot Injection Into - NASA

The Seeker is primarily searching for existing technologies or research studies, outside of the aircraft industry, that provide surface friction reduction in fluid mediums and have potential to be translated to the aircraft industry for skin friction reduction. Other sources of aircraft drag reduction …

body drag shock: Topics by WorldWideScience.org Numerical calculations are presented for both skin friction and (unseparated) pressure drag for turbulent boundary-layer flows over a fuselage-like body with wall heat transfer. A History of suction-Type Laminar-Flow control ensued in the United States from the mid-fuel reduction. It also identified additional Yenkee YMS 3028RD Resistance - Gaming mouse | Alzashop.com
