... with sloshing is addressed. The numerical method is explained briefly and its advantages and shortcomings are addressed. It is shown that the egg concept has a much smaller hydroelastic response than the bucket concept for the same material properties. closed fish cage elastic sloshing FEM BEM FSI...

Prediction of Performance of Tip Loaded Propeller and its Induced Pressures on the Hull

Seungnam Kim, Spyros A. Kinnas
Proc. ASME. OMAE2020, Volume 6B: Ocean Engineering, V06BT06A055, August 3–7, 2020
Publisher: American Society of Mechanical Engineers
Paper No: OMAE2020-18999
https://doi.org/10.1115/OMAE2020-18999
... Abstract In this paper, a boundary element method (BEM) is applied to a tip loaded propeller (TLP) to predict its open water characteristics and induced hull pressures under fully-wetted and uniform inflow. Tip of a TLP blade has a winglet-like tip plate on the pressure side to improve...
