<p>This thesis describes an experimental study of hydrodynamically suspended cylinders and cylinders modified by end cap(s) in a vertical pipeline, using water and polymer solution as the fluid medium.</p> <p>The experiments involved hydrodynamically suspending steel and aluminium cylinders in a pipeline for the sphere to pipe diameter ratios of 0.434 to 0.864. Drag coefficients were found from a force balance which involved measuring the average velocity of flow near the cylinders as well as the pressure drops across the cylinders. The experiments on cylinders were done in both water and dilute aqueous polymer solutions, while the tests on cylinders modifies by end caps were done in water only. The length to diameter ratios of cylinders used in this study ranged from three to fourteen.</p> <p>Comparison of results from this study of those obtained by other authors especially Hoerner(¹³), McNown & Newlin(¹⁸) and Aly^(³⁰) were made.</p> / Master of Engineering (ME)
