Abstract: Flow devices and a methods for guiding flow are disclosed. The examples disclosed herein relate to a flow device (50) including a first line system (60) for conducting a first fluid flow (100), wherein the first line system (60) comprises a guide pipe (21) and at least one guide means (20, 22) influencing a flow direction of the fluid flow (100) such that the fluid flow (100) between an inflow region (61b) and an outflow region (62b) of the first line system (60) in a circulation-flow region (105) at a circumferential angle UW circulates in a radially encircling manner about an inflow axis (102) and/or an outflow axis (103). The examples disclosed herein furthermore relate to a method for guiding a fluid stream (10) which has an inflow portion (12) and an outflow portion (13) having substantially parallel, preferably coaxial inflow and outflow axes (14, 15).

Abstract: A dynamo-electric machine includes a stator and a rotor interacting with the stator and including a laminated core. A shaft configured for rotation about an axis is connected to the rotor in a torsion-resistant manner. Arranged at least on an axial front side of the rotor is a brake which includes a brake rotor that is directly connected to the laminated core of the rotor.

Abstract: Turbomachines having guide ducts are disclosed. One disclosed example turbomachine includes a rotor rotatable about an axis of rotation and having rotor blade ducts, a housing having housing ducts to allow the inflow or outflow of working medium and guide blade ducts fixed in the housing, where the rotor blade ducts are in fluid communication with the housing ducts via the guide blade ducts.

Abstract: A turbomachine has a housing which has at least one inflow channel. A plurality of blades is arranged on a rotor wheel and an operating medium flows toward the blades. The operating medium flows via the inflow channel into at least one blade channel which is formed between two blades mounted on the rotor. After exiting the rotor region, the operating medium enters a diffuser. A guide body deflects the operating medium flowing out of the blade channel in the direction of the diffuser. A portion of the guide body in the turbomachine is positioned in an intermediate region of the rotor. The intermediate region is surrounded in the radial direction by the rotor blades and lies between a blade-channel outlet and an inlet opening in an outlet channel which is downstream of the rotor and is formed by the diffuser.

Abstract: Systems for generating energy are disclosed. An example system for generating energy includes an internal combustion engine that is to load a shaft with a torque. The internal combustion engine is to generate waste heat. A Rankine cycle plant is to be fed waste heat from the internal combustion engine to operate therewith a turbine coupled to a first electric generator. The first electric generator is connected to an electric motor which is coupled rotationally to the shaft to introduce an additional torque. The internal combustion engine is to drive a second electric generator. The second electric generator is to feed electric current into a high-power network configured to provide electrical power in a megawatt range.

Abstract: An electrical machine includes a stator having circumferentially arranged winding heads, with a winding head space being defined radially beneath the winding heads. Interacting with the stator is a rotor which has a rotatable laminated core. A magnetic brake is received in the winding head space and includes a magnet module having at least one permanent magnet which is axially resiliently fixed and constraint against rotation and which is magnetized in an axial direction, and an electromagnet which is arranged axially adjacent to the permanent magnet and securely fixed thereto. The electromagnet produces a magnetic field with a main direction oriented in an axial direction. Interacting with the at least one permanent magnet and the electromagnet is a ring-shaped armature which is secured directly and rigidly to the rotor so as to establish a fixed rotative engagement between the armature and the rotor.

Abstract: A method is provided for reducing natural organic fouling levels in contaminated ion exchange resins by contacting the resins with an oxidizing agent solution.
