To improve the energy extraction performance of the oscillating hydrofoil. the lift force that acts on the oscillating hydrofoil is analyzed. The pressure difference between the oscillating hydrofoil‘s opposing surfaces is dominant to generate the lift force. Forming and shedding of the leading-edge vortex from the hydrofoil surface determines the pressure difference between the... https://www.markbroyard.com/hot-offer-greenery-gatefold-wedding-invitations-discount-mega-find/
