continuity law and bernoulli law in maneuvering





In simple explanation, when there is increment of water speed at stern part ( due to reduced area - according to continuity law -  assuming contant Axv) then  after that bernoulli law take places ( assuming constant stern and bow part). The stern part (where the water speed became increased) now will cause low pressure at that area and meantime high pressure at bow. This difference in the pressure cause the ship to experience " bank suction".

diffraction waves

Ships, buoys, barges, floating docks, breakwaters, submersibles supporting oil drilling rigs, and so on, are all structures whose safety and performance depend on their response to waves. In a calm sea, the body weight, the buoyancy force, and possible forces from external constraints such as ten- sion legs, keep the body in static equilibrium. In waves, the presence of a sufficiently large body causes diffraction (scattering) of waves. The body must absorb some of the incident wave momentum and therefore must suffer a dynamic force. If the constraints, such as the mooring lines, are not sufficiently rigid, the body oscillates, hence further radiates waves, and ex- periences reacting forces from the surrounding fluid and from the constraint. Since the reacting forces depend on the motion of the body itself, the body, the constraint, and the surrounding water are dynamically coupled in the presence of incoming waves. from: THEORY AND APPLICATIONS OF OCEAN SURFACE WAVES i...

how propeller works - impulse theory

source: file.pdf impulse theory is the most basic to propel a ship in the impulse theory, the pressure is changing. Low pressure is before, and high pressure after blades. And the pressure become stabilized at certain time. ( basic: bernoulli law - pressure velocity stuffs)
