Abstract
A double-sided fluidic oscillator, includes a primary feedback loop unit, a secondary feedback loop unit with two outlet and one inlet, and a common mixing chamber. Two perpendicular oscillator jets operating at different oscillation frequencies produce perpendicular and bi-stable pulsating flow oscillations, simultaneously. The proposed design of the fluidic oscillator is a double-sided fluidic oscillator. Also, disclosed is a method of achieving an enhanced heat and mass transfer by better mixing due to the wide sweeping pattern over a target surface using the double-sided fluidic oscillator.
Claims11
A fluidic oscillator, comprising:
- a primary feedback loop unit comprising a single inlet and a single mixing chamber;
- a secondary feedback loop unit in fluid communication with the single inlet and the single mixing chamber of the primary feedback loop unit;
- and
- at least one outlet;
- whereby fluid entering the single inlet of the primary feedback loop unit produces at least two perpendicular oscillator jets operating at different oscillation frequencies, thus producing perpendicular and bi-stable pulsating flow oscillations, simultaneously, wherein switching of fluid occurs between the primary and secondary feedback loop units for achieving sweeping jet patterns.
