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 fluid-type absorption dynamometer that includes a rotary impeller and one or more of a variety of features that enhance the shaft-horsepower range for which the dynamometer can be used. One of these features is a variable restriction intake that allows a user to adjust the flow of fluid to the impeller. Other features are a unique impeller shroud and shroud guide that are each movable relative to the impeller to allow a user to adjust flow characteristics at the exhaust and blade regions of the impeller. Yet another feature is a set of exhaust baffles that facilitate an increase in the range of shaft power ratings of the device and the reduction of deleterious vibration and noise. The dynamometer also includes impeller blades having a unique configuration.

摘要： The present invention is a system (20) for controlling various fluid flows, e.g., secondary fluid flows including cavitating fluid flows, typically developed along the shroud line and usually in or around a leading edge (21) within a flow channel (22) of a compressor or pump impeller (23) and inducer/impeller (24). System (20) includes a plurality of devices for controlling various flow conditions. In one embodiment, system (20) includes a diffuser device (27) for stabilizing cavitating flows, a bypass device (28) for re-injecting flow upstream, and a flow control device (30) for selectively directing secondary fluid flow to either the diffuser device or the bypass device. In addition, at very high flow rates, bypass device (28) may also serve as a high-flow, forward-bypass device. Devices (27) and (28) form a pathway for secondary fluid flows, including cavitating flows, around a first portion (31) of a housing (32).

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.

摘要： A radial turbo machine has an impeller and a diffuser with a plurality of airfoil vanes. The airfoil vanes have a design point angle of attack substantially equal to or less than the angle of attack corresponding to the classic onset of pressure side stall of the airfoil vane. The pressure side of the airfoil vane faces away from the rotational axis of the impeller while the suction side faces towards the impeller's rotational axis.
