An Analysis of Skimboard Hydrodynamics

N.D. Barnett[1], and E. Gutirrez-Miravete[2]
[1]General Dynamics-Electric Boat, Kingston, Rhode Island, USA
[2]Rensselaer at Hartford, Hartford, Connecticut, USA

This paper report on a study of the hydrodynamics of skimboards and surfboards using the computational fluid dynamics (CFD) module in COMSOL. The study analyzes the flow in a thin water layer underneath a skim board in a 2-D Cartesian coordinate. Three different sets of boundary conditions were employed and one of them produced the best agreement with previous findings.
