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.
Highlights
EPJ Web of Conferences commercial solvers have been frequently used for complicated geometry cases [13,14,15,16], for the laminar channel flow with multiple circular synthetic jets [14, 15]
The initial step for the experiments is the flow visualization, which is performed in quiescent water without channel flow for f=15Hz and Re = 177, i.e. U0 = 0.059 m/s
The visualization is qualitative in character, it is helpful for an idea of an impinging synthetic jets (SJs) interaction near the exposed wall
Summary
EPJ Web of Conferences commercial solvers have been frequently used for complicated geometry cases [13,14,15,16], for the laminar channel flow with multiple circular synthetic jets [14, 15]. Because of the difficulties associated with experimental work at the micro-scale level, the present numerical and experimental investigations of this case are performed at the meso-scale (the channel cross section size is in order centimeters)
