Abstract

A numerical and experimental study of multiple circular synthetic jets interacting with low Reynolds number laminar channel flow is presented. Flow velocity and temperature fields in channel are computed using three-dimensional computational model under a meso-scale. The working fluid is air. Moreover, flow visualization in water is performed under approximately double size. The computed flow field and heat transfer distribution on the wall are compared with the experimental results.
