  4. 3. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Mahsa Darvishghanbar; [2022]
    Nyckelord :;

    Sammanfattning : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. LÄS MER
