... aerodynamic performances are then presented and discussed in Section 4. Finally, time-resolved LBM data are introduced and analyzed in Section 5. All the tests were performed in the VKI high speed axial compressor rig R4 (Figure 1). The test section (H25) discharges the flow into a large collector...

...Ahmad Fikri Mustaffa; Vasudevan Kanjirakkad Purpose This paper aims to understand the aerodynamic blockage related to near casing flow in a transonic axial compressor using numerical simulations and to design an optimum casing groove for stall margin improvement using a surrogate optimisation...

...Mohammad Reza Pakatchian; Hossein Saeidi; Alireza Ziamolki Purpose This study aims at enhancing the performance of a 16-stage axial compressor and improving the operating stability. The adopted approaches for upgrading the compressor are artificial neural network, optimization algorithms...
