The comparative research on the VPMM experiment and numerical simulation of the SUBOFF model
Journal of Physics: Conference SeriesAbstract To ensure optimal maneuvering performance of underwater vehicles, it is essential to obtain highly precise hydrodynamic coefficients for constructing the equations of motion. The principal approach to acquiring these coefficients is through the Planar Motion Mechanism (PMM) test.

The Hydrodynamic Noise Suppression of a Scaled Submarine Model by Leading-Edge Serrations
Journal of Marine Science and Engineering, 2019 High hydrodynamic noise is a threat to the survival of underwater vehicles. We investigated a noise suppression mechanism by putting leading-edge serrations on the sail hull of a scaled SUBOFF model, through numerical calculation and an experimental test.
