Filed: 2002-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a blade which can obtain dynamic lift larger than that of a conventional blade under the same condition and which prevents fluid separation, and to provide a more efficient impeller which prevents occurrence of cavitation.  <P>SOLUTION: The figure shows that the amount of fluid flowing along an upper surface of the blade is made larger than the amount of fluid flowing along a lower surface of the blade by discharging the fluid from a front edge of the blade to thereby increase the dynamic lift, and further shows that the fluid separation is prevented because the direction of the fluid flowing along the upper surface of the blade is changed by letting the fluid flow. When the figure is made upside down, it shows the operating state of a vane of the impeller in the fluid. Swirls which are generated when the fluid flows to the rear portion of the vane are prevented by discharging the fluid from a front edge of the vane. The figure also shows that the cavitation which occurs at the front edge of the vane is restrained.  <P>COPYRIGHT: (C)2004,JPO
