Contamination and Distortion of Steady Flow Field Induced by Various Discrete Frequency Disturbances in a Aircraft Gas Turbines.
Abstract
The objective of this investigations was to acquire a fundamental understanding of two aerothermodynamic effects of vortices as related to aircraft gas turbines: (a) the total temperature and total pressure separation; and (b) the negative entropy spots. In the period covered here, the theoretical explanation for (a) has been finished and it was found that the separation of total temperature and pressure is caused by the time-varying static pressure field around vortices; they were in favorable agreement with the preliminary experimental results obtained by an aspiration probe. Preparations for the search of negative entropy spots around vortices were also made. Keywords: Karman vortex street, negative entropy.
