Abstract
A fluidic oscillator is disclosed for providing oscillating flow to outlet ports (172, 173). The fluid oscillator (100) in one embodiment has no fluid communication between a pair of diverging diffuser legs (163, 164) downstream of the upstream edge (169) of a splitter (165) and no fluid communication between a chamber (162) and either of the diverging diffuser legs downstream of the splitter edge. In other embodiments, a turbulent flows generator is formed by use of bump step (202), pins (220, 230), surface discontinuities (250) or a combination thereof.
