Project Description and Objectives

Flow over cylindrical structures are common phenomena in engineering, such as offshore structures, bridge piers and skyscrapers. However, the flow separation and alternating vortex shedding in the downstream wake could cause significant increases in the mean drag and lift fluctuations and serious structural vibrations, which is known as vortex-induced vibration (VIV). Over the past few decades, various passive and active open-loop control techniques were developed to suppress vortex shedding behind a circular cylinder. The use of splitter plates as a passive control method has been extensively investigated both experimentally and numerically, owing to the simple geometric configuration and easy implementation.


Although many investigations have indicated that the presence of splitter plates greatly affects the wake regimes or characteristics, few works in the literature studied the influence of splitter plates on the wake transition of bluff bodies. The main purpose of this project is to study the influence of splitter plates on the wake transition of bluff bodies.
