Molao-motheo oa ho lekanya
Mokelikeli o phallang ka lebelo le itseng 'me o feta tšitiso e tsitsitseng o hlahisa maqhubu.The generation of vortices is known as Karman's Vortices. The frequency of vortex shed is a direct linear function of fluid velocity and frequency ho itšetlehile ka sebōpeho le sefahleho bophara ba 'mele oa bluff.
Kaha bophara ba tšitiso le bophara bo ka hare ba phala bo tla fokotseha kapa bo fokotsehe, maqhubu a fanoa ke poleloana e reng:
f=STV/d
Ka foromo:
f - Karman vortex frequency e hlahisoang ka lehlakoreng le leng la 'mele oa bluff (Hz)
Nomoro ea St - strouhal (nomoro e seng ea mahlakore)
V - lebelo le tloaelehileng la mokelikeli (m/s)
d - bophara ba 'mele oa bluff (m)
