High-Fidelity Coupled CFD/MBD for Vehicle Operation in Very Shallow Water and the Surf Zone
Abstract
This project aims at developing computational fluid dynamics (CFD) and multibody dynamics (MBD) capabilities to simulate operation of vehicles in very shallow water and the surf zone. The coupled CFD/MBD code will also incorporate externally computed non-linear waves to simulate realistic shoreline breakers. Validation of the code and models will be performed againstcanonical problems and exp"erimental data for wave systems, and against specific vehicle experiments performed in this project by other teams. Simulations will" be performed for various Test Environments including maneuvers in the surf zone and sea to shore and shore to sea maneuvers with and without wheel deployment. Simulations will also be performed to produce data to develop reduced-order models in the Large Amplitude Motion Program System (LAMPS) framework and potentially other simulation codes. The vehicles of interest will be a jet ski/all ter"rain vehicle hybrid with retractable wheels, and a second heavier vehicle to be determined. The high-fidelity base tools to be used"" are the CFD code REX and the MBD code IMBD, both developed at The University of Iowa. Relevant implementations as part of this prog""ram includedevelopment of a MBD library to couple IMBD to high or low fidelity flow codes, development of bottom contact capabiliti""es including complex terrain models, and coupling with a high-fidelity large-scale nonlinear wave code.
