Dynamic response of elliptical cylinders undergoing transverse flow-induced vibration

J Zhao, K Hourigan, MC Thompson - Journal of Fluids and Structures, 2019 - Elsevier
While the flow-induced vibration (FIV) of a circular cylinder has been characterised in
considerable detail, the FIV of elliptical cylinders has not received similar attention. This …

Varying Magnus effect on a rotating sphere at intermediate Reynolds numbers

A Sareen, K Hourigan, MC Thompson - … Journal of Heat and Fluid Flow, 2024 - Elsevier
Rotating bluff bodies are known to experience a side force due to a well-known
phenomenon called the Magnus effect. The Magnus effect is evident in many sports (cricket …

[HTML][HTML] A framework for processing wave buoy measurements in the presence of current

AC Pillai, T Davey, S Draycott - Applied Ocean Research, 2021 - Elsevier
