- H102 Optimization of Hydrofoil Air Pump for Reduction of CO_2 Emissions from Ships
抄録
We have invented a new power-saving device for ship drag reduction by microbubbles in order to reduce the CO_2 emissions from ships. The new device, which consists of angled hydrofoils with air introducers, has been installed on a coaster and 〜10% net power saving is achieved. This device utilizes a low-pressure region produced above the hydrofoil as the ship moves forward, which drives the atmospheric air into the water. Here we present its principal and optimization of the device based on laboratory experiments on hydrofoils moving beneath a free surface. Especially, the flow behaviors of the entrainment through the interface and bubble formation process are discussed.
