متن کاملDesign of Pneumatic Diffuser System
During non-generation periods, leakage through the wicket gates of a hydroturbine often results in very poor quality water (low or zero dissolved oxygen) in the tailrace of the hydropower facility. Generally, the leakage rate is relatively small, usually about 5-10 cfs per turbine. A bottom-mounted diffuser system was designed based on laboratory-measured and manufacturer-supplied specification...
متن کاملNumerical Investigation of the Campbell Diffuser Concept
Campbell diffusers have a unique feature in that they lack axial symmetry in the end walls. It has been proposed that the asymmetry of the end wall in a vaned diffuser can be tailored to improve its performance. This concept is applied to the redesign of two vaned diffuser configurations: (1) diffuser with straight leading edge; (2) diffuser with parabolic leading edge. In the redesign, the ori...
متن کاملImpeller Volute and Diffuser Interaction
The flow in centrifugal pumps is exceedingly complex, involving curvature, system rotation, separation, turbulence, and secondary flows. Moreover, the geometry is often asymmetric due to the volute shape. As a result, the relative motion between impeller and volute generates an unstableness which affects not only the overall pump performance, but is also responsible for pressure fluctuations, h...
متن کاملAn approach towards a perfect thermal diffuser
A method for the most efficient removal of heat, through an anisotropic composite, is proposed. It is shown that a rational placement of constituent materials, in the radial and the azimuthal directions, at a given point in the composite yields a uniform temperature distribution in spherical diffusers. Such arrangement is accompanied by a very significant reduction of the source temperature, in...
