Abstract: Five closed-cycle gas turbine cogeneration plants have been built and commissioned in the Federal Republic of Germany. In all cases the working fluid was air. The facilities were designed as ...

Abstract: The only commercially running closed-cycle gas turbine in the world delivering electricity as well as heat to a public utility and a heating network, is the heat and power station in Coburg, ...

Abstract: The mainly nonstationary operation of a solar-heated receiver can be simulated with sufficient accuracy only if data about the dynamic behavior are available. For this reason, the dynamic behavior ...

Abstract: The transformation of energy in the stages of high-reaction axial compressors can be considerably increased if the rotor blading consists of tandem cascades. This also involves aerodynamically ...

Abstract: During the operation of turbines the surfaces of the blades are roughened by corrosion, erosion and deposits. The generated roughness is usually greater than that produced by manufacture. The ...

Abstract: In the mass flow range −1.3 ≤ m/m N ≤ + 1.3 (N = nominal point) and in the speed range −1.0 ≤ n/n N ≤ +1.0 the four-quadrant characteristic of a turbine stage was completely measured. ...

Abstract: Solar energy can be converted effectively into electrical or mechanical energy. The radiant heat of the sun is collected by a parabolic dish, concentrated intensely, and reflected into a cavity ...

Abstract: For operation of a gas turbine in single-cycle arrangement with a high-temperature reactor, rupture of a main circuit pipe has to be included in the safety considerations. In the event of ...
