The device has a flow network comprised of four symmetrical working chambers connected with a pump chamber. The pump chamber is actuated by a PZT diaphragm. The flows in the device are studied by a computational fluid dynamics simulation and experimental measurements. The numerical simulation is carried out with programmable open source OpenFOAM, where the vibration of the PZT diaphragm is modeled with a newly developed boundary condition. Flow inside the device is verified by two hotwires embedded in each working chamber. It was confirmed that the flows generated in the four sensing chambers were almost identical. The performance of the device can be customized either by fluidic parameters, such as the driving voltage on the diaphragm, or by heat transfer processes, such as heating current of the hotwire or by alternating the gas media. The device is robust, ready-to-use and minimal in size. These are important features that can contribute to the development of multi-axis fluidic inertial sensors, fluidic amplifiers, gas mixing, coupling and analysis. date: 2016-02 date_type: published publisher: Elsevier official_url: http://www.sciencedirect.com/science/journal/09254005 full_text_status: public publication: Sensors and Actuators B: Chemical volume: 223 pagerange: 820-826 refereed: TRUE issn: 0925-4005 citation: Dau, Van Thanh and Dinh, Thien Xuan and Bui, Thanh Tung (2016) Jet flow generation in a circulatory miniaturized system.
