	Fluidická oscilátorová ústrojí založená na „Aerodynamickém Paradoxu“ Tesař, Václav Discussed unusual flow-induced oscillation mechanism is based on an old but nearly forgotten phenomenon contradicting simple logic (motion opposing the direction of incoming flow). The author proposed using this mechanism in a number of interesting fluidic devices. The paper concentrates on observed existence of two different vibration regimes and the fact that the transition between these regimes exhibits a local maximum of Strouhal number Sh. Detailed record
	Tlakem poháněná mikrofluidika Tesař, Václav Microfluidics is a new field of fluid flow generation and control at small scales, making possible fundamental changes in some engineering and biomedical fields. Particular advantages bring devices operating without moving parts – but at the usually small Reynolds number it is difficult to use jet inertia,upon which no-moving-part fluidics is based. The paper presents, on an example, a solution: flow assisted - or downright driven - by applied pressure difference. Detailed record
	Mechano/fluidická zařízení využívající „aerodynamický paradox“ Tesař, Václav A mechanism of aerodynamically excited vibration of a movable or elastic solid body was investigated and suggested for use in a number of fluidic (or mechano/fluidic) devices. The vibration is based on a phenomenon little known and so far practically not used, despite of its very old history. The effect leads to an alternatingdirection of a fluid force acting a movable object exposed to fluid flow. One of the directions is interesting: it is the very opposite to what an uninitiated observer may expect. Early investigations of this "paradox" by the present author in 1971 became recently of renewed interest because of the possible topical use in biosensors. Detailed record
