I-SUP-LUGB Vortex flowmeter ngaphandle kobushushu kunye nembuyekezo yoxinzelelo

• Umgaqo wokulinganisa

  Ulwelo oluqukuqela ngesantya esithile kwaye ludlula umqobo osisigxina luvelisa i-vortices.Ukuveliswa kwee-vortices kwaziwa ngokuba yi-Karman's Vortices. Ubuninzi bokuchithwa kwe-vortex ngumsebenzi othe ngqo wesantya solwelo kunye nobuninzi bezantya ezixhomekeke kwimilo kunye nobubanzi bobuso bomzimba we-bluff.

Ekubeni ububanzi bomqobo kunye nobubanzi bangaphakathi bombhobho buya kuba ngaphezulu okanye ngaphantsi, ukuphindaphinda kunikwa ngokuthetha:

f=STV/d

Kwifomula:
f - I-Karman vortex frequency yenziwe kwelinye icala lomzimba we-bluff (Hz)
Inombolo ye-St - strouhal (inombolo engeyo-dimensional)
V – isantya esiphakathi solwelo (m/s)
d – ububanzi bomzimba we-bluff (m)
