摘要：
The influence of synthetic jets on heat transfer rate along a flat plate has been studied for laminar and turbulence cross-flow and at several exciting frequencies (0 < f < 12.8 Hz). To better understand such interactions, both cross-flow field without and with synthetic jets in a quiescent environment were preliminarily reviewed. The influence of their confrontation on flow structure was studied, particularly for a frequency of 12.8 Hz and the roles of this frequency as well as four others on heat transfer coefficient were determined. Lastly, the influence of cross-flow velocity with its fluctuating activity on synthetic jet development was closely observed. (C) 2017 Elsevier Ltd. All rights reserved.
