Numerical study of the 3D Savonius turbine under stationary conditions
TL;DR: In this article , a one-way fluid-structure interaction (FSI) simulation with the Ansys Workbench environment 2019 R3 is used to predict the flow structures and the force response of various turbine diameters (D) from size 1D until 5D at different wind speeds (8 m/s < v < 18m/s) and bucket angles (0°-180°).

Hydro-elastic computational analysis of a marine propeller using two-way fluid structure interaction
TL;DR: This study reveals that metallic (NAB) propeller can be replaced by a composite propeller and the acoustic response from two-way FSI analysis will be more realistic due to the consideration of hydro-elastic effect of propeller.

Modified wind energy collection devices for harvesting convective wind energy from cars and trucks moving in the highway
TL;DR: In this article , a comparison of different wind energy collection devices (WECDs) is studied in the highway in order to determine which WECD can collect more wind energy, and the results show that the order of the maximum Cp generated by the WECDs is CT > RT > BT.
