Anemometer na ƙarfin kwayoyi

Makarantar

Anemometer mai karamin zafiya shi ne wani taurari na iya amfani da ita don bincike tsari da yanayi na abubuwa mai yawa. An yi wannan taurari tare da kan neman zafiya daga fili mai karfi da aka kara a kan zafiya. Filin ya kama karfi saboda kirkiro cikin zafiya, kuma yanayin filin ya zama alama na kayan zafiya.

Idan filin mai karfi an kara a kan zafiya, zafiya ta karya zafiya daga filin, kuma haka ta haɗa tsaron filin. Yawan ƙarin filin (saboda yanayin tsari) ya fi girma da yanayin zafiya, kuma haka ta ba da kyau a maimaita tsari.

Tana da gaba-gaban da ake amfani da ita a fannin zafiya don bincike masana'antar zafiya mai yawa. Tana da muhimmanci a cikin littattafai na zafiya don bincike kayan zafiya mai yawa.

Bunshi

Anemometer mai karamin zafiya tana da waɗannan bunshuka:

• Fili Mai Karfi
  

• Wani fili mai karfi da ke kusa (kamar platinum, tungsten) wanda ake juye a kan wurin mai sauƙi ko mai kirkiro.

• Fili tana da ƙarin zafiya, kuma tana da shiga a kan zafiya tare da kan neman tsari da yanayi.

• Kayan filin tana koma daga wurin zuwa ƙasar wasu aiki don kawo a kan circuitry na maimaita.

• Circuit Bridge Wheatstone

• Wani circuit elektriko mai ma'ana na iya amfani da ita don maimaita yawan ƙarin filin.

• Bridge tana da kyau a neman yawan ƙarin filin saboda karyar zafiya, kuma tana haɗa haka a kan maimaita tsari na zafiya.

Yadda Ake Amfani Da Ita: Hukumar Kirkiro Daidaito

• Tsarin: Probe na anemometer tana da shiga a kan zafiya da ke buƙata tsari.

• Karfin Fili: Wani kirkiro elektriko daidaito tana kara a kan filin, karfin ita zuwa tsari mai karfi da zafiya.

• Karyar Zafiya: Idan zafiya ta karya a kan filin, tana karya zafiya, kuma haka ta haɗa tsaron filin. Tsari masu karfi masu karyar zafiya suna haɗa da karyar zafiya mai yawa, kuma haka ta haɗa da tsaron filin mai yawa.

• Maimaita Ƙarin: Circuit bridge tana maimaita ƙarin filin, wanda tana rage da tsari (saboda yanayin tsari). Circuit tana da kyau a kan voltage daidaito, kuma haka tana haɗa da ƙarin filin a kan maimaita tsari na zafiya.

Ayyukan Da Ake Amfani Da Su

• Bincike a aerodynamics, hydrodynamics, da boundary layer flow.

• Maimaita tsari na zafiya a pipelines, HVAC systems, da wind tunnels.

• Binciken zafiya a oceans, atmospheres, da biological systems.

Muhimmanci

• Maimaita da ma'ana ga karyar zafiya masu karfi (ideal for turbulent flow analysis).

• Tsarin mai kadan tana da kyau a maimaita a wurare.

• Maimaita daidaito na tsari da yanayi na zafiya da orientation na probe daidaito.

Idan filin mai karfi tana da shiga a kan zafiya, zafiya tana karya zafiya daga filin. Adadin zafiya da aka karya tana da girma da ƙarin filin. Idan karyar zafiya tana rage, ƙarin filin tana rage. Circuit bridge tana maimaita ƙarin filin, kuma haka tana haɗa da adadin zafiya na zafiya.

Hukumar Tsari Daidaito

A cikin hukumar, wani kirkiro elektriko tana kara a kan filin. Idan filin mai karfi tana da shiga a kan zafiya, zafiya tana karya zafiya daga filin, kuma haka ta haɗa tsaron filin. Hukumar tana da kyau a haske tsari filin daidaito saboda karyar zafiya.

Mechanism feedback tana ƙara kirkiro elektriko a kan filin a baya-bayan lokaci don kawo karyar zafiya. Adadin kirkiro daidaito da ke buƙata da take haɗa da tsari filin tana da girma da tsari na zafiya: tsari masu karfi masu karyar zafiya suna buƙata da kirkiro masu karfi. Hakan tana ba da kyau a maimaita tsari da yanayi na gas ko liquid.

Maimaita Tsari Na Zafiya Ta Hanyar Anemometer Mai Karamin Zafiya

A cikin anemometer mai karamin zafiya, kirkiro elektriko tana kara a kan filin mai karfi da ke shiga a kan zafiya. Circuit bridge Wheatstone tana amfani da ita don maimaita tsari filin tare da maimaita ƙarin filin, saboda ƙarin tana da girma da tsari.

A cikin hukumar tsari daidaito (wani hukumar da ake amfani da shi), tsari filin tana daidaito saboda karyar zafiya. Mechanism feedback tana ƙara kirkiro heating a baya-bayan lokaci don kawo karyar zafiya, kuma haka tana haɗa da circuit bridge. Adadin kirkiro daidaito da ke buƙata da take haɗa da tsari daidaito tana da girma da tsari na zafiya, kuma haka tana ba da kyau a maimaita tsari.

Resistor standard tana da shiga a kan filin mai karfi. Kirkiro da ke kara a kan filin tana da kyau a maimaita tare da potentiometer.

Karyar zafiya daga filin mai karfi tana da kyau a maimaita tare da wannan equation:

Daga:

• v = tsari na zafiya,

• ρ = density na zafiya,

• a da b = constants da suka da girman tsari, properties physical na zafiya, da filin.

Idan I shine kirkiro a kan filin da R shine ƙarin, a equilibrium:

Ƙarin da tsari instrument tana daidaito don maimaita tsari na zafiya tare da maimaita kirkiro I.

Wannan setup tana amfani da ingantaccen heat transfer, ƙarin elektriko, da fluid dynamics don bayyana maimaita tsari na zafiya a cikin applications, daga laboratory research zuwa industrial process control.

Ta haka, anemometer mai karamin zafiya tana da muhimmanci a cikin scientific da engineering disciplines don maimaita tsari na zafiya da ma'ana.
