摘要：

We present a steady-state dive trajectory prediction method for an autonomous underwater vehicle. The method couples RANS CFD simulation data of flows over the hull of the Trawl Resistant Self-Mooring AUV (TRSMAUV) with force equilibrium equations to calculate the velocity and pitch angle of the vehicle in an unpowered negatively buoyant dive. The model results are compared with a time-resolved motion coupled CFD simulation and experimental results from TRSMAUV field trials. The steady-state model estimates the trajectory of the TRSMAUV with good agreement with experimental results at minimal computational cost compared to the motior coupled simulations.
