Experimental Measurements of Waves and Vessel Dynamics in the Surf Zone for Modeling and Simulation Validation
Abstract
In this project, we propose to perform full-scale experiments on an amphibious ATV/PWC in order to: 1) Collect CFD-quality validatio""n data describing the shoaling and breaking of waves of varying heights, types, and wavelengths on a sandy beach; 2) Measure vehicle"" thrust, steering, and 6-DOF motions for an amphibious ATV/PWC in calm water and non-breaking waves for thevalidation of simulated"" vehicle maneuvering; and 3) Measure the vehicle motions during transit of the surf line, outer surf region, inner surf region, and"" run-up region, including thrust and 6-DOF motions, ground contact force, and vehicle traction. Tests will be conducted in a large o"utdoor wave flume capable of generating realistic surf conditions. The collected data will be used as a validation dataset for the development of high-fidelity simulations that couplecomputational fluid dynamics (CFD) with multi-body dynamics (MBD) to simulate the dynamics of an amphibian during the land/sea transition. These efforts support the development of a modeling and simulation (M&S) environment for the design and benchmarking of future amphibians designed to operate autonomously in the littoral zone.
