摘要： PROBLEM TO BE SOLVED: To provide a propeller jet flow generating device that effectively achieve an improvement of a thrust efficiency by preventing generation of cavitations by making a propeller wake distribution uniform, and an improvement of the thrust efficiency by reducing a swirl flow downstream of a propeller by forming an inverted flow upstream of the propeller. SOLUTION: A propeller jet flow generating device 100 includes a pump 5 serving as a sea water intake/eject means for taking sea water SW from an intake port 2 provided to a ship bottom 1 therein and ejecting the taken sea water SW toward the rear of a ship body from an ejection port 4 provided to a stern 3. The device generates a jet flow 7 toward a propeller 6 attached on a rearward part of the ship body relative to the ejection port 4. As the sea water intake/eject means, a cooling sea water intake means of a ship equipment 8 is used. In addition, at least one of an ejecting amount and an ejecting direction of the sea water SW being ejected from the ejection port 4 is changeable. In addition, the inverted flow is formed upstream of the propeller 6 by the generated jet flow 7. COPYRIGHT: (C)2011,JPO&INPIT
