摘要： A wall attachment fluidic device operating in the laminar flow range is disclosed. Either bistable or monostable devices can be produced, provided the attachment wall associated with each stable state conforms to a particular shape. That particular shape is one in which the radius of curvature K of the attachment wall is initially substantially equal to x1/2, where x is a nondimensional distance measured along the arc of the wall for the power jet inlet. The radius of curvature K gradually increases until it reaches x3/4. Thereafter, it remains equal to x3/4 until the jet receiver is reached.
