Physics-Based Simulation of AUV Forced Diving by Self-Propulsion

It is necessary to predict accurately the maneuverability of autonomous underwater vehicle (AUV) diving by self-propulsion to improve its safety and stability. A method was presented to predict the vehicle’s forces and flow details in real time during forced diving motion. A full appended model was...
