SUP-LUGB Vortex flowmeter me ka ʻole o ka mahana a me ka uku pānaʻi

• Ana kumu

  ʻO ka wai e kahe ana me ka wikiwiki a me ka hele ʻana i kahi keʻakeʻa paʻa e hoʻopuka i nā vortices.Ua ʻike ʻia ka hanauna o nā vortices ʻo Karman's Vortices. ʻO ke alapine o ka vortex shedding he hana laina pololei o ka wikiwiki o ka wai a me ke alapine e pili ana i ke ʻano a me ka laula o ka maka o ke kino bluff.

No ka mea o ka laula o ke keakea a me ke anawaena o loko o ka paipu e oi a emi mai paha, ua haawiia ke alapine e ka olelo:

f=StV/d

Ma ka papa kuhikuhi:
f - Karman vortex frequency i hana ʻia ma kekahi ʻaoʻao o ke kino bluff (Hz)
St – helu strouhal (helu ʻole-dimensional)
V – ka māmā māmā o ka wai (m/s)
d – laula o ke kino bluff (m)
