Flow Around Bluff Bodies With Corner Modifications On Cross-Sections, Rujun Liu

Master's Theses and Capstones

This research aims to illustrate how the flow around a cylinder changes when the cylinder’s cross-section is systematically changed from square to circle by modifying the corner radius.

Numerous research studies have been performed on the flow around circular cylinders and square cylinders leading to a relatively complete understanding of them. In the early 20th century, von Kármán and Rubach described the theoretical basis and provided an analytical solution to the flow around circular cylinders at low Reynolds number. Later, experiments on the flow around square cylinders were conducted by Nakaguchi, Bearman, and other researchers. However, until now, only a …

Interdependence Of Flow And Shape Morphological Dynamics For Flow-Induced Erosion Of Bluff Bodies, Michael Paul Allard

Doctoral Dissertations

Flow-induced erosion encompasses all processes in which fluid-solid interactions result in the

removal and transport of material from the solid. The removed material may change its physical

state and/or chemical composition and may be redeposited onto the solid body or advected away

by the fluid and deposited elsewhere. Common to all flow induced erosion processes is that they

involve an eroding surface, and eroding agent, and a fluid flow which delivers the eroding agent to

the eroding surface. Consequently, the study of erosion is difficult as it requires detailed knowledge

of the material, mechanical, and/or thermophysical properties of the eroding …
