Equivalent simulation method for total pressure distortion of ship inlet
Frontiers in Energy ResearchAccording to the use of marine gas turbines, inlet distortion is caused by the bending of the compressor inlet port. The total pressure distortion is the external stability reduction factor that has the greatest impact on the engine’s aerodynamic ...

Experimental Investigation on the Correlation between Total Pressure and Swirl Distortions
Journal of Engineering for Gas Turbines and Power, 2023 Abstract To lay the foundations of establishing low-cost methods which can predict characteristics of swirl distortion inexpensively, experimental investigations on the correlation between total pressure and swirl distortions of a typical S-duct intake model are implemented. Baffle plate is installed at the inlet of the intake model to generate
