Umgoqo wezikhukhula ozenzakalelayo we-hydrodynamic wakhiwe izingxenye ezintathu: uhlaka lwaphansi, iphaneli ejikelezayo kanye nengxenye yokuvala udonga oluseceleni, engafakwa ngokushesha ekungeneni nasekuphumeni kwezakhiwo ezingaphansi komhlaba. Amamojula aseduze ahlukaniswa kalula, futhi amapuleti enjoloba aguquguqukayo nhlangothi zombili avala kahle futhi axhume iphaneli yezikhukhula ngodonga.
