Ua haujlwm hom ntawm anemometer anemometer
Lub anemometer yog ib qho ntsuas ntsuas ceev uas hloov cov teeb liab ntws tawm mus rau hauv cov teeb liab hluav taws xob, thiab tuaj yeem ntsuas cov dej kub lossis qhov ntom ntom. Lub hauv paus ntsiab lus yog hais tias ib tug nyias hlau hlau rhuab los ntawm hluav taws xob (hu ua kub hlau) yog muab tso rau hauv lub airflow, lub tshav kub dissipation ntawm kub hlau nyob rau hauv lub airflow muaj feem xyuam rau cov khiav ceev, thiab lub tshav kub dissipation ua rau kub hloov ntawm lub cov hlau kub ua rau muaj kev hloov pauv hauv kev tiv thaiv, thiab cov teeb liab ntws tawm tau hloov mus rau hauv hluav taws xob teeb liab.
Nws muaj ob hom kev ua haujlwm:
①Txoj kev ntws tsis tu ncua. Tam sim no los ntawm cov hlau kub tseem nyob tas li. Thaum qhov kub thiab txias hloov, qhov tsis kam ntawm cov hlau kub hloov, yog li qhov hluav taws xob hla ntawm ob qhov kawg hloov, yog li ntsuas qhov ntws ntws;
② Hom kub tsis tu ncua. Qhov kub ntawm cov hlau kub yog khaws cia tsis tu ncua, xws li 150 degree, thiab tus nqi ntws tuaj yeem ntsuas raws li qhov xav tau tam sim no.
Cov hom kub tsis tu ncua yog siv dav dua li hom ntws tsis tu ncua.
Ntxiv rau qhov zoo tib yam ib leeg-xaim, cov hlau kub kuj tseem tuaj yeem ua ke ob-xaim lossis peb-xaim hom los ntsuas qhov nrawm ntawm txhua qhov kev qhia. Cov hluav taws xob teeb liab tso tawm los ntawm tus xov tooj hotline yog nkag mus rau hauv lub computer tom qab amplification, them nyiaj thiab digitization, uas tuaj yeem txhim kho qhov ntsuas qhov tseeb, tuaj yeem ua tiav cov ntaub ntawv tom qab ua tiav cov txheej txheem, thiab nthuav cov kev ntsuas ceev, xws li ua tiav cov nqi tam sim thiab lub sij hawm nruab nrab tus nqi, ua ke ceev thiab ib nrab ceev, thiab turbulence. thiab lwm yam kev ntsuas ntawm turbulence parameters.
