    摘要: A turbomachine that includes a radial-flow impeller and one or more of a variety of features that enhance the performance of machinery in which the turbomachine is used. For example, when the turbomachine is used in a dynamometer, the features enhance the useful shaft horsepower range of the dynamometer. One of the features is a variable-restriction intake that allows for adjusting flow rate to the impeller. Other features include a unique impeller shroud and a shroud guide each movable relative to the impeller. Yet another feature is an exhaust diffuser that facilitates an increase in the range of shaft power and the reduction of deleterious vibration and noise. The turbomachine can also include a unique impeller blade configuration that cooperates with the adjustable intake and the exhaust diffuser to enhance flow through the turbomachine.

    摘要: A turbomachine has a set of vanes in the airfoil cascade of its diffuser system. A first portion of the vanes are "rogue" vanes. A second portion of the vanes are "remaining" vanes. For a given flow through the vane set, the angle of incidence of the rogue vanes differs from the angle of incidence of the remaining normal vanes. The remaining vanes may be free-floating or positionable. The rogue vanes can be fixed or scheduled to dominate flow through the diffuser system, thereby improving efficiency of operation. Optionally, additional "intermediate" vanes can be disposed between the "rogue" vanes and the "remaining" vanes. In a centrifugal pump or compressor, the "rogue" vanes are positioned such that a preponderance of the flow will proceed through the impeller, subsequently through the rogue vanes, and then smoothly into the volute so that flow will pass smoothly through the system with minimum frictional effects and maximum pressure recovery. For centrifugal or axial turbomachines, the use of one or more sets of rogue vanes creates a "channelizing" effect of the flow throughout the entire turbomachine.

    摘要: The present invention is a device (100) for at least partially stabilizing an unstable fluid flow within a flow channel (103) by capturing at least a portion of the unstable fluid within a vaneless diffuser having a diffuser slot (104). The present invention also includes maintaining and harnessing a substantial portion of the energy contained in the fluid as it flows through the diffuser in order to utilize the fluid to improve the condition of the flow field. An example of a beneficial use includes discharging the diffuser effluent into the flow at other points critical to instability, hence reducing the overall instability of the flow channel.
