This project is acutely focused on the fundamental fluid physics governing the unsteady loads experienced by non-streamlined objects. Bluff bodies, as they are commonly known, experience abrupt separation of the flow which subjects them to the consequences of flows which may be unsteady and in many cases, transitioning from laminar towards turbulence. Examples of bluff bodies include tall buildings, bridge decks, and slung-load containers. One archetype geometry which has proven itself to be a benchmark for other studies is the rectangular prism. This work makes extensive use of the rectangular geometry, which is defined by its aspect ratio (L/h) along with more traditional aerodynamic parameters such as angle of attack, and Reynolds number, Re. The effort to understand and predict these loads is pursued primarily through experimental testing and analysis as well as a supplementary effort to apply linear stability methods where applicable.
