TWO-DIMENSIONAL POISEUILLE FLOW IN A GROOVED CHANNEL
摘要
This paper describes a Poiseuille flow between two walls, one of which has grooves normal to the streamwise direction. Three Reynolds numbers are studied (Re = 1000, 5000, 10000) and comparisons between visualization and the velocimetry measurements are presented. The visualization is performed by particle-streak visualization and measurement method is Particle Image Velocimetry (P.I. V.). Measurements enabled the detection of coherent structures and the evolution of velocity in the cavities and in the gap. The present study has been developed to demonstrate that it can provide accurate data in micro-grooves for future experiments with a Couette flow.
