Abstract

Synthetic jet flows from piezoelectric actuators have been investigated for flow control in the field of fluid dynamics. Numerical simulation for a single diaphragm piezoelectric actuator operating in quiescent air is performed to investigate the complex flow field around the slot exit. A periodic velocity transpiration condition is used to simulate the effect of the moving diaphragm. Numerical aspects of the artificial dissipation and time integration schemes are investigated. Results for the flow field around the slot exit agree well with the experimental data. The k-ω shear stress transport model gives superior results to the Spalart-Allmaras model and a linear version of the k-ε Craft model.
