    Numerical investigation of steady air injection flow to control rotating stall in centrifugal compressors حسب Halawa, Taher

    منشور في 2014
    "…Numerical model was built to simulate high speed transonic centrifugal compressor working at an operating point close to surge. Air was injected at 12 locations at the vaneless region between the impeller and the diffuser at shroud surface with 5 different injection angles and 3 different injection mass flow rates. …"
