  • EFFECT OF NOZZLE GEOMETRY ON THE ATOMIZATION

    The nozzle aspect ratio has a more significant effect on the near-field jet stream characteristics for both fluids than the orifice inlet shape. Longer nozzles (l /d = 20) form more stable jet streams and delay the breakup of sheets, leading to greater breakup length than that attained with shorter nozzles (l /d = 5). For similar Reynolds ...
