Cov yam ntxwv thiab kev siv tseem ceeb ntawm anemometer
nta
1. Qhov loj me, me me cuam tshuam rau qhov chaw ntws;
2. Kev siv ntau yam. Nws tuaj yeem siv tsis tau tsuas yog rau cov pa roj xwb tab sis kuj ua kua, thiab tuaj yeem siv rau hauv subsonic, transonic thiab supersonic flows ntawm gases.
3. Cov lus teb siab txog li 1 MHz.
4. Kev ntsuas qhov tseeb thiab rov ua tau zoo. Qhov tsis zoo ntawm cov xov hlau kub anemometer yog qhov kev sojntsuam cuam tshuam nrog cov dej ntws, thiab cov hlau kub yog yooj yim tawg.
5. Ntxiv rau qhov ntsuas qhov nruab nrab qhov nrawm, nws kuj tseem tuaj yeem ntsuas tus nqi pulsation thiab turbulence; Ntxiv rau qhov ntsuas qhov kev taw qhia ib leeg, nws tseem tuaj yeem ntsuas qhov nrawm nrawm hauv ntau cov lus qhia tib lub sijhawm.
Lub hom phiaj tseem ceeb
1. Ntsuas qhov nrawm thiab kev taw qhia ntawm qhov nruab nrab ntws.
2. Ntsuas lub pulsation tshaj tawm ntawm cov khoom ntws thiab nws cov zaus spectrum.
3. Ntsuas cov Reynolds kev ntxhov siab nyob rau hauv turbulent flow thiab ceev dependence thiab lub sij hawm dependence ntawm ob lub ntsiab lus.
4. Kev ntsuas phab ntsa shear kev ntxhov siab (feem ntau yog los ntawm kev siv cov yeeb yaj kiab kub sojntsuam tso dej yaug nrog cov phab ntsa, lub hauv paus ntsiab lus zoo ib yam li cov hlau kub velocimetry).
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.
