• Ƙa'idar aunawa

  Ruwan da ke gudana tare da wani ƙayyadadden gudu da wuce kafaffen toshewa yana haifar da vortices.An san ƙarni na vortices da Karman's Vortices.Yawan zubar da vortex aiki ne na layin kai tsaye na saurin ruwa kuma mita ya dogara da siffar da faɗin fuskar jikin bluff.

Tun da nisa na toshewa da diamita na ciki na bututu zai zama ƙari ko žasa da tsayi, ana ba da mitar ta hanyar magana:

f=StV/d

A cikin tsari:
f - Karman vortex mita da aka haifar a gefe ɗaya na jikin bluff (Hz)
Lambar St-strouhal (lambar mara girma)
V – matsakaicin saurin ruwa (m/s)
d - Nisa na bluff jiki (m)
