title = "PIV measurements of laminar flow around a hemisphere",
abstract = "This paper presents an experimental study of laminar flow past a smoothed hemisphere using the Particle Image Velocimetry technique. The experimental setup consists of a rectangular channel, through which water flows over a 30-mm diameter hemisphere mounted on a horizontal surface. From the measured velocity distribution around the hemisphere a physical insight into the flow is presented. Vertical and horizontal 2D velocity distributions are obtained for a constant Reynolds number of Re=800, corresponding to a regime of laminar flow. Measurements revealed the three dimensional structure of the flow including a horseshoe vortex surrounding the hemisphere and arch-shaped vortices in the downstream region. Both instantaneous and average velocity distribution were studied. The location of the reattachment point, the separation line, and the reverse flow are identified and discussed.",
