New version of DEA compressor for a novel hybrid gas turbine cycle: TurboDEA

This study is aimed at introducing new version of DEA compressor and turboDEA, a novel gas turbine cycle that is specially configured to work by this compressor. This paper explains a preliminary study based on computer modeling for evaluating potential of the concept to heighten gas turbine technology. The paper is started by explaining mechanism of DEA compressor operation and its components, and is followed by designing a sample DEA compressor. Besides capability to adaptation to environmental elements, such a compressor potentially can operate with considerably less energy than conventional types. To show advantages of DEA compressor, performances of a sample turboDEA and its counterpart turbojet are calculated and compared. The comparison shows considerably low fuel consumption and higher flexibility of turboDEA beside turbojet. The study also presents performance sizing of the sample DEA compressor based on proper non-dimensional quantities, which shows its superior ability to adapt to environmental elements and user demands. Finally, cell actuator as the key part of DEA compressor is modeled and analyzed by ANSYS Multiphysics package.
