A LAMINAR CHANNEL FLOW EFFECTED BY SYNTHETIC JETS ? EXPERIMENTAL AND NUMERICAL STUDIES

Popis výsledku v původním jazyce

This study deals with a laminar channel flow interacting with a synthetic jet, with emphasis on low Reynolds numbers. The study is predominantly experimental, with supporting numerical simulations. The experiments were performed with water as the workingfluids, and two methods were used: Laser Doppler Vibrometry for measurement of membrane oscillations, and PIV. The experimental and numerical results confirmed that the channel flow can be effectively controlled by means of the synthetic jet. As a result of the synthetic jet propagation through the channel flow, two significant effects were found: an oblique jet impingement and an overall modification on the channel flow more downstream the impingement area. Based on these local and overall effects, apossibility of heat/mass transfer enhancement was deduced. The authors suggest that this technique can be used for desirable augmentation of various applications.
