Abstract: This paper outlines the handling of a semi-closed cycle gas turbine, its working fluid is carbon dioxide and the fuel is low heating value gas from coal; however, at startup air and natural ...

Abstract: The centrifugal impeller is one of the most critical aerodynamic parts of centrifugal compressors. The previous experimental investigation demonstrated that the fully shrouded impeller is better in terms of efficiency ...

Abstract: There is a difference of opinion regarding the relative merits of gas turbines using biomass fuels. Some engineers believe that the internal combustion gas turbine coupled to a gasifier will ...

Abstract: By being exposed to atmospheric conditions gas turbines are inevitably subjected to sources of fouling. The resulting degradation can be partially recovered by cleaning the compressor. Based on ...

Abstract: The centrifugal impeller is one of the most critical aerodynamic parts of centrifugal compressors. The previous experimental investigation demonstrated that the fully shrouded impeller is better in terms of efficiency ...

Abstract: The improvement of performance simulation for gas turbines has been approached in very different ways. In particular for high-bypass turbofans, efforts have been made to investigate radial flow ...

Abstract: A tool to evaluate the turbine cooling air schedule during the flight path is presented. The method is suitable for complex gas turbine engine models where accurate calculation of thermodynamic ...

Abstract: Two-dimensional (2D) compressor flow simulation software has always been a very valuable tool in compressor preliminary design studies, as well as in compressor performance assessment operating ...

Abstract: Traditionally, engine performance has been simulated based on nondimensional maps for compressors and turbines. Component characteristic maps assume by default a given state of inlet conditions ...
