Yinto eqhelekileyo ukusebenzisa umoya opholileyo othe nkqo ukupholisa iinkukhu kwixesha elishushu lasehlotyeni.Kufuyo lwamaqanda oluxinana kakhulu, isantya somoya kwiinkukukufuneka ifikelele ubuncinane kwi-3m/s, kwaye isantya somoya kwindlu yeenkukhu kwindawo ezinobushushu obuphezulu kunye nobushushu obuphezulu kufuneka sifikelele ngaphezu kwe-4m/s ukuze ufumane “impembelelo yokupholisa umoya” engcono.
“Impembelelo yokupholisa umoya” ikakhulu ibhekisa kwisantya somoya ukunciphisa ubushushu bomzimba weenkukhu.
Isantya somoya sinokuba nefuthe elingakanani kubushushu bomzimba weenkukhu?
Ngokophononongo olwenziwe yiYunivesithi yaseGeorgia, isantya somoya sinyuke ukusuka kwi-0m/s ukuya kwi-2.54m/s.Ubushushu bomzimba weenkukhu buzakwehla ngaphezulu kwe-6°C.”
Ukuze ufumane isantya esiphezulu somoya, ndiyinto eqhelekileyo kukwenzaindlu yenkukhuisilingi, nciphisa ubude behoko yeenkuku, okanye ukusuka kumphezulu wehoko yeenkuku ecaleni kophahla olunxantathu ngokuthe nkqo ezantsi kuwo wonke umgama othile ukufakela isithinteli-moya okanye ikhethini yokunqamla umoya ukunciphisa indawo enqamlezileyo yehoko yenkukhu ukuphucula isantya somoya. ehokweni.
Kutheni ukwenza oku, ikakhulu ngenxa yokuba isantya somoya sisondelelene nommandla onqamlezileyo weinkuku.
Ukubalwa kwesantya somoya kwihoko yenkukhu enexesha elide: isantya somoya = umthamo wokungenisa umoya / indawo enqamlezileyo yehoko
Kucacile kule fomyula ukuba ukunyusa isantya somoya we-coop, mhlawumbi ukwandisa umoya we-coop, okt ukwandisa inani labalandeli abaxhathisa uxinzelelo olubi, okanye ukunciphisa indawo ye-cross-sectional ye-coop.
Ukwandisa abalandeli kuthetha ukunyuka kweendleko, ukwandisa ukusetyenziswa kombane, ukunyuka kweendleko zokugcina, kwaye ekuhambeni kwexesha ukongeza iindleko ezibalulekileyo zokusebenza kwishishini.
Emva koko ukunyusa isantya somoya kufuneka kuthathelwe ingqalelo ekunciphiseni ummandla onqamlezileyo weinkuku.Ngezantsi siqonda utshintsho lwenkukhu yenkukhu ngaphambi nangemva kokunyusa ikhethini lokuthintela umoya ngezibalo ezithile.
Umzekelo: ihoko yenkukhu i-12m ububanzi, i-100m ubude, iindonga ezisecaleni ze-hoop ziyi-2.4m ukuphakama, umbindi wehoko (eyona iphakamileyo) yi-4.8m, i-hoop ifakwe kunye ne-10 50 intshi ye-fan, amandla okungenisa umoya fan ngalinye -50 Pa i 31000m³/h.
Emva koko isantya somoya sehoko yenkukhu kufuneka sibe: isantya somoya = umthamo wokungenisa umoya / indawo enqamlezileyo = 31000 / 3600× 10 / [12× (4.8 + 2.4) / 2] = 86.1/43.2 = 1.99m / s
Ukuba sifaka isilingi okanye ikhethini yomoya kwihoko yenkukhu, ukuze ukuphakama komphezulu wehoko okanye umphetho ophantsi wedrape ukusuka emhlabeni ube yi-3.6m, kwaye ukuphakama kwamacala omabini ehoko kuhlala kungatshintshi. isantya somoya yi = 31000/3600×10/[12×(3.6+2.4)/2]=86.1/36=2.39m/s
Ngoko ke, kwimeko yenani elifanayo labalandeli, ngokunciphisa indawo enqamlezayo yendlu yeenkukhu inokunyusa isantya somoya ngesiseko se-0.4m / s yasekuqaleni, oko kukuthi, ukusebenza kakuhle kwanda ngama-20%, Utshintsho lwesantya somoya oluveliswa yimpembelelo yokupholisa umoya lukwahlukile, umahluko phakathi kwempembelelo yokupholisa umoya emibini ehambelana nobushushu obumalunga ne-2.℃, kwimeko yobushushu obuphezulu obuphezulu, umahluko wobushushu obuyi-2℃kwanele ukwenza ingozi enkulu kwiinkukhu.
