This process is experimental and the keywords may be updated as the learning algorithm improves.īushnell, D. These keywords were added by machine and not by the authors. International research on stabilization by suction, referred to as LFC with suction, was intensive at the same time and culminated in the United States in the 1960’s with flight tests of a relatively unswept suction glove on an F-94 aircraft (Reference 3) and X-21 flight tests (References 4–7) of a totally new swept LFC wing on a reconfigured WB-66 aircraft. Stabilization of boundary-layer disturbances and instabilities by pressure gradient and shaping became known as natural laminar flow (NLF), and NACA research led to the development of the six-series NLF airfoil. (An excellent summary of this work is presented in References 1 and 2.) Research was performed in many countries to explore approaches for achieving extensive laminar flow with these concepts. Send us feedback.Research in the area of laminar flow control (LFC) dates back to the 1930’s when early applications of stability theory led to the observation that laminar boundary layers can be stabilized by either favorable pressure gradients or small amounts of wall suction. ![]() These example sentences are selected automatically from various online news sources to reflect current usage of the word 'laminar flow.' Views expressed in the examples do not represent the opinion of Merriam-Webster or its editors. Rob Verger And Charlie Wood, Popular Science, 2 Dec. 2020 The vehicle’s blimpy shape and rear propeller are designed to create an aerodynamic phenomenon called laminar flow, in which the air travels in smooth layers over the craft. ![]() Tim Dahlberg, Star Tribune, The vehicle’s blimpy shape and rear propeller are designed to create an aerodynamic phenomenon called laminar flow, in which the air travels in smooth layers over the craft. ![]() 2021 The laminar flow of the wind seems to be optimum, too, which should make calculations easier for Bryson DeChambeau. 2021 The front end features tiny, hard-to-spot fins and holes designed to create a perfect laminar flow along the body of the car. 2022 But if laminar flow works so well, why aren't all planes designed like this? - Jacopo Prisco, CNN, 5 Nov. 2022 If the shape of the car generates a good laminar flow along the bodywork, the tufts will stream in that direction. Rachel Simon, Better Homes & Gardens, 3 Oct. Albert Folch, Discover Magazine, The EPA WaterSense certified faucet also features a spout made with laminar flow, which helps conserve water during use. Recent Examples on the Web The fluids and particles in laminar flow follow paths that are mathematically predictable – a necessity for precision engineering and medical device design.
