Taw qhia rau cov kev siv tseem ceeb ntawm anemometers
Lub anemometer yog ib qho cuab yeej uas ntsuas qhov ceev ntawm huab cua ntws. Nws muaj ntau hom, thiab feem ntau siv ib qho ntawm cov chaw nres tsheb huab cua yog lub khob cua anemometer;
Nws muaj peb lub khob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Lub concave nto ntawm lub khob khoob yog tag nrho cov taw qhia nyob rau hauv ib qho kev taw qhia.
Tag nrho qhov kev nkag siab yog ntsia rau ntawm txoj kab ntsug rotating. Nyob rau hauv qhov kev txiav txim ntawm cua quab yuam, lub khob cua rotates nyob ib ncig ntawm lub axis ntawm ib tug ceev proportional rau cua ceev.
Lwm hom rotating anemometer yog lub kiv cua anemometer, uas muaj peb-los yog plaub-hniav propeller raws li qhov kev xav;
Nruab nws nyob rau pem hauv ntej ntawm ib tug weathervane kom nws taw tes nyob rau hauv cov kev taw qhia ntawm cua txhua lub sij hawm. Cov hniav tig ib ncig ntawm kab rov tav axis ntawm qhov nrawm proportional rau cua ceev.
Anemometers muaj ntau yam kev siv thiab tuaj yeem siv tau yooj yim hauv txhua qhov chaw. Lawv tau siv dav hauv hluav taws xob, hlau, petrochemical, kev txuag hluav taws xob thiab lwm yam lag luam;
Muaj lwm daim ntawv thov hauv Beijing Olympic Games. Kev sib tw caij nkoj, kev sib tw rowing, kev sib tw tua hluav taws, thiab lwm yam txhua yam yuav tsum tau siv cov anemometers rau kev ntsuas.
Niaj hnub no cov anemometers yog qhov siab heev. Ntxiv rau qhov ntsuas cua ceev, lawv tuaj yeem ntsuas cua kub thiab cua ntim.
Muaj ntau lub lag luam uas yuav tsum tau siv anemometers. Cov kev lag luam pom zoo muaj xws li: kev lag luam nuv ntses, ntau yam kev lag luam kiv cua, kev lag luam uas yuav tsum tau muaj cua tshuab thiab tso pa tawm, thiab lwm yam.
Kev siv tseem ceeb ntawm anemometer:
1. Ntsuas qhov nruab nrab ntws ceev thiab kev taw qhia.
2. Ntsuas lub pulsation ceev thiab spectrum ntawm cov khoom ntws.
3. Ntsuas qhov kev ntxhov siab ntawm Reynolds nyob rau hauv turbulent flow thiab lub nrawm sib raug zoo thiab lub sij hawm correlation ntawm ob lub ntsiab lus.
4. Ntsuas phab ntsa shear kev ntxhov siab (feem ntau yog ua los ntawm kev siv cov yeeb yaj kiab kub sojntsuam tso dej yaug nrog phab ntsa, lub hauv paus ntsiab lus zoo ib yam li kev ntsuas kab ceev).
5. Ntsuas cov kua dej kub ( ntsuas qhov hloov nkhaus ntawm qhov kev sojntsuam tsis kam nrog cov kua dej ua ntej, thiab tom qab ntawd txiav txim siab qhov ntsuas kub raws li qhov ntsuas qhov ntsuas tsis kam.
