Small-width wall-attached Coandǎ jets for flow control

Autor: Oussama El Mokkadem, Xintong Chen, Charlene Phan, Jérôme Delva, Pierric Joseph, Antoine Dazin, Francesco Romanò

Publikováno v: Flow, Vol 3 (2023)

The flow dynamics of small-width wall-attached jets generated by a Coand-effect nozzle is investigated by unsteady Reynolds-averaged Navier–Stokes simulations. The data are validated by comparison with hot-wire velocity measurements performed on th

Sensors and Actuators A: Physical, Elsevier, 2019, 291, pp.39-47. ⟨10.1016/j.sna.2019.03.034⟩

International audience; Sweeping jets are an emerging type of actuators that have gained interest due to their potential use in flow control applications. The working principle of these devices is based on the bi-stable attachment of a jet to adjacen

Single hot-wire velocity measurements have been conducted along a three-dimensional measurement grid to capture the flow-field induced by a 45 $$^\circ$$ inclined slotted pulsed jet. Based on the periodic behavior of the flow, two different estimatio

Experimental Measurement Benchmark for Compressible Fluidic Unsteady Jet

Autor: Pablo Fernandez, Jerome Delva, Celestin Ott, Philipp Maier, Quentin Gallas

Publikováno v: Actuators, Vol 7, Iss 3, p 58 (2018)

A benchmark of different measurement techniques is presented to characterize the dynamic response of a synthetic jet actuator working in compressible regime. The setup involves a piston-based synthetic jet, as well as the benchmarked measurements are
