Study of the possibility to add piezoelectric sensors on boat hulls and investigation of shear stress caused by drag

Poster (konferens), 2025

Reducing flow resistance of underwater vehicles is of great importance to reduce energy consumption in maritime transportation. In this paper, we present numerical simulations and experimental methods for structural health monitoring of boat hulls, using self-powered piezoelectric sensors to assess shear/drag forces. The studies are based on drag tests on an immersed plate using piezoelectric sensors placed in different locations. Simulations are done using COMSOL Multiphysics. The numerical results show good agreement with experimental sensors’ voltage output measured at various speeds.
