Numerical and experimental analysis of membrane with piezoelectric element used for synthetic jet flow control

摘要

Synthetic jet generators have been widely ana-lysed in controlling the airflow of aircrafts aiming to en-hance aircraft lifting and manoeuvrability, control stalls, and reduce the noise level. One of the best choices is to use piezoelectric actuators in the design of such kind of the devices because of its favourable properties. This article presents a numerical and experimental modal analysis of the membrane with bonded piezoelectric element Sonox P502. The aim of this investigation was to find suitable piezoelectric actuator for controlling synthetic jet flow. And in order to check the suitability and reliability of the received data about the piezoelectric membrane, experi-mental analysis of the synthetic jet generator was per-formed. The CTA (Constant Temperature Anemometers) technique is very sensitive and was used for the determina-tion of frequencies and velocity of flow.
