Abstract A remotely operated vehicle was designed and tested to assess the hydrodynamic coefficients calculation techniques. Drag terms were found using steady Computational Fluid Dynamics simulations. Added mass terms were found through unsteady CFD simulations for Planar Motion Mechanism test. System dynamics from experimentation and nonlinear simulator using coefficients was compared to judge them. Results showed that added mass terms were correctly estimated while rotational drag terms were erroneous and linear ones were acceptable |
