A Tesla Valve, sometimes called a Tesla's Valvular Conduit,〔 Sean Michael Ragan. ("The Tesla Valve: One Way Flow With No Moving Parts" ). 2012. 〕 is a valve allowing for a fluid to flow very preferentially (or entirely) in one direction, but without the moving parts usually found in valves. The principle is that currents flow along different paths in different directions, and that these differences have a disproportionate effect on the resistance of the valve. Named after Nikola Tesla, it was invented in 1916 ((U.S. patent 1,329,559 ); patented 1920). In practice, the idea has seen little development or use since its invention. A similar mechanism is used for mixing on a small scale through the use of a Coanda effect mixer. Tesla valve offers resistance 10-200 times greater in one direction compared to the other, in which the flow is turbulent. ==See also== * Coanda effect 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tesla valve」の詳細全文を読む スポンサード リンク
