Abstract: As a sequel to the first and second reports of the present series of experiments intended to gain knowledge on the effect of surface roughness on hydromechanical characteristics, particularly ...

Abstract: It has been demonstrated that profiles can be found which manifest extremely favorable characteristics when used as blade elements of a given cascade formation. The method of developing such ...

Abstract: In previous reports, theory [1, 2] and experiments [3–7] were discussed on profiles that promised to possess desirable characteristics when incorporated into cascades of given arrangement. These ...

Abstract: It was proved experimentally that the conditions of cavitation incipience, such as the positions of incipient cavitation bubble formation and collapse, extent of cavitation, and the propensity ...

Abstract: With a view to clarifying cavitation phenomena induced by ultrasonic waves, utilized recently in erosion tests, the frequency spectrum of the waves caused by cavitation was obtained, and the ...

Abstract: In pursuit of the studies previously reported [1–3], three profiles suited for application in the main blade elements of high head Kaplan turbines—two intended for sections near boss and one ...

Abstract: Experiments were undertaken to determine the effect of cavitation on the discharge coefficient of venturi tubes of Herschel type, and on additional limitations that must be applied to existing ...

Abstract: The object of this paper is to investigate the effects of cavitation on the discharge coefficient of sharp-edged orifice plates with reference to various degrees of cavitation as defined by a ...

Abstract: The effect of surface roughness on hydrofoil characteristics, particularly cavitation performance, was studied experimentally. It was intended to initiate the first of a series of studies to ...
