SUP-LUGB Vortex flowmeter kaore he pāmahana me te utu pehanga

• Te kaupapa ine

  Ko te wai e rere ana me te tere o te tere me te haere i tetahi arai pumau ka whakaputa i nga porangi.Ko te reanga o nga pooro e mohiotia ana ko Karman's Vortices. Ko te auau o te whakahekenga vortex he mahi ahorangi tika o te tere wē me te auau i runga i te ahua me te whanui mata o te tinana bluff.

I te mea ko te whanui o te aukati me te diameter o roto o te putorino ka nui ake, ka iti ake ranei te noho tonu, ka tukuna te auau e te korero:

f=StV/d

I roto i te tātai:
f – Karman vortex auau i hangaia ki tetahi taha o te tinana bluff (Hz)
St – tau strouhal (tau ahu-kore)
V – tere toharite o te wai (m/s)
d – te whanui o te tinana pari (m)
