... interaction with rotor passage core flow. Six different vortex generator configuration are investigated by varying distance between vortex generator trailing edge and rotor leading edge. Particular vortex generator configuration shows maximum improvement of stall margin and operating range by 5.5% and 76.75...

... with improves both compressor stall margin as well as stage efficiency. Hence in the current work, as an innovative idea, effect of casing treatment slot along rotor tip mean camber line is investigated on NASA 37 compressor stage. Casing treatment slot with rectangular cross-section was created along the rotor...

The slot length of 20 to slots [4], [5], bend slots [6], semicircular slots [7], etc. Osborn et 100% of Ca, depth of 15.7% Ca and skew angle of 60o resulted in al. [8] demonstrated the maximum stall margin improvement the best compressor...

... travels nearly at half the rotor speed. Keywords: Transonic, axial flow compressor, stall margin, rotating stall 1. INTRODUCTION Aero engine performance is mainly governed by one of the rotating components namely axial flow compressor. Transonic axial compressor stages are the most preferred compressors...

... wake fluid. Considering the positive effects of crenulation in a cascade, it was hypothesized that the same technique would work in a rotating compressor to enhance its performance and stall margin. However, the present CFD simulations on a transonic compressor rotor have given mixed results. Whereas...

... This paper presents the results of numerical studies on the effect of endwall reshaping on the performance and stall margin of a centrifugal compressor. The endwall (shroud) of a baseline compressor was reshaped by introducing a convex hump at a location downstream of the inducer where the flow...

... Axial Transonic Compressor J-Shaped Casing Treatment Stall Margin CFD Gas Turbine Casing Treatment (CT) is one of the passive methods to increase the stability margin of the compress and hence that of the aircraft jet engines. In this paper, a novel J-shaped axial CT slot geometry...
