| Summary: | Drag reduction is an important research topic to address to the growing economic
and environmental global concerns. Results had suggested that stream-wise riblets in
sharks seem to be the act of work in reducing drag. However, as riblet surface was
found to have dust accumulation problem, it is of the author’s interest to find out if
dimple can be used as a substitute instead. This project seeks to investigate the drag
reduction effect caused by the flow over a single spherical dimple using RANS and
LES turbulence models. |
