Drag force acting on biofouled net panels

WebAug 22, 2014 · The net deformation was determined with an optical tracking system, and the forces on the net panels were measured with a multi-axis force/torque sensor system. It is shown that bending stiffness and density of nets affect net deformation, as both parameters impact the balance between drag and gravitational forces on the nets.
