We constructed a closed-loop water tunnel with an optically accessible round cross section test section machined with interchangable contracting or expanding geometry. Solid acrylic spheres of substantial size (3-12mm in diameter) were introduced into the flow upstream, and their movement through the varying geometry was recorded. In our forthcoming presentation, we will detail our experimental design, compare flow field statistics with and without the spheres, and discuss the dynamics of the spheres as they navigate through the changing pipeline geometry. Our preliminary results indicate that this technique offers valuable insights into the behavior of particulate flow within constricted or expanding pipelines.
