Turbomachines such as air dynamometers are disclosed that include a radial outflow compressor and gas collector. In some examples, the gas collector is designed as a separate component that is coupled to the machine, such as coupled to a frame. In some examples, the collector and frame are intentionally spaced and coupled at discrete points to minimize the transfer of mechanical and thermal energy therebetween. Aspects of the present disclosure also include turbomachines that include at least one impeller bypass flow path for the direct transfer of air between ambient and a location in the collector downstream of the impeller blades. In some examples, such flowpath(s) may allow for the inflow of external ambient air into the collector. Methods of manufacturing turbomachines having decoupled collectors are also disclosed.
Turbomachines having one or more flow guiding features designed to increase the performance of the turbomachine. In some examples, flow guiding features are designed and configured to bias a circumferential pressure distribution at a diffuser inlet toward circumferential uniformity, otherwise account for such low-frequency spatial pressure variations, increase the controllability of spatial flow field variations, or modifying flow field variations, etc. In some examples, a diffuser having a row of vanes that include a plurality of first vanes and at least one second vane having a different characteristic than the first vanes are disclosed. In some examples, diffusers having an aperiodic section including one or more biased passages for biasing a flow field are disclosed.

Flow control devices and structures for turbomachines. In some examples, the flow control devices and structures include various arrangements of flow guiding channels, partial height vanes, and other treatments located on one or both of a shroud and hub side of a turbomachine to redirect, guide, or otherwise influence portions of a turbomachine flow field to thereby improve the performance of the machine.
A rotor bearing system includes a mandrel and a plurality of canted cantilever bearing pads supporting the mandrel, such that, when the bearing pads are run-in against the mandrel, the bearing pads generate uniform bearing gaps and alignment. The mandrel and the bearing pads are sized to form a running proximity to exclude the entry of red blood cells or flow entrained contaminant inclusions therebetween during operation, thereby causing the bearing system to operate in an elasto-hydrodynamic regime of mixed- or boundary-lubrication.

The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

Centrifugal turbomachines, such a centrifugal compressors, centrifugal blower, and centrifugal pumps, having unique treatments that enhance their performance ranges. In one arrangement, the treatment involves injecting a relatively high-momentum flow proximate to the blade-tip clearance gap at the inlet to the impeller of the turbomachine in a manner that reenergizes flow at the gap. The injected high-momentum flow can be taken from a location downstream of the outlet of the impeller and/or from a flow external to the turbomachine. In another arrangement, the non-self-bleed-type treatment involves providing the centrifugal turbomachine with a secondary flow path upstream of the inlet to the impeller. In one example, the flow of working fluid to the secondary flow path is modulated according to the mass flow of the working fluid. During times of higher flow, the secondary flow path is opened, and at times of lower flow, the secondary flow path is closed.

A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

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.
A high-pressure system and method utilizing an input fluid. The system includes a reactor treating a material to produce an effluent having an energy content, a plurality of stages compressing the input fluid in a stepwise manner providing a high-pressure reactor input stream to the reactor, and a cascading effluent energy recovery system mechanically communicating with the plurality of stages. The cascading effluent energy recovery system imparts a portion of the energy content of the effluent into each of the plurality of stages powering that stage. The method includes receiving an input fluid, compressing the input fluid over a plurality of stages producing the high-pressure stream, providing the high-pressure stream to the reactor, recovering a portion of the energy content of the effluent at each of the plurality of stages, and using each the portion of the energy in compressing the input fluid at a corresponding respective stage.
A system and method for automatically generating a computation mesh for use with an analytical tool, the computation mesh having a plurality of ξ-grid lines and η-grid lines intersecting at mesh points positioned with respect to an inner boundary and an outer boundary. The system and method includes receiving information corresponding to a shape to be analyzed, ξ-grid line mesh parameter value corresponding to a desired number of ξ-grid lines for the computation mesh, and an η-grid line mesh parameter value corresponding to a desired number of η-grid lines for the computation mesh, and generating the computation mesh from one or more mesh equations without the need for receiving additional information from a user. In one example, the solving of the one or more mesh equations includes an outer boundary distance parameter that is a function of an inner boundary distance parameter and one of a natural log of the η-grid line mesh parameter value and a square root of the η-grid line mesh parameter value.
