Uhlalutyo lokuvuza kweGesi eNtshayo kwiGumbi leSinyanzelo seGesi yeNdalo

I-molecular diffusion yindlela ebalulekileyo yokudluliselwa kwezinto, Ngethuba nje kukho i-concentration gradient (umahluko wokuxininisa) kunye noxinzelelo lwe-gradient, umgangatho wegesi yendalo uya kutshintshela ngokuzenzekelayo ukusuka kwindawo yoxinzelelo oluphezulu ukuya kwindawo yoxinzelelo oluphantsi kunye nokusuka kwindawo ephezulu indawo yoxinzelelo oluphantsi de uxinzelelo kunye nokugxininiswa kufikelele ekulinganisweni.Ukuvuza kwerhasi etshayo kwigumbi lokuxinzelela igesi yendalo kwenzeka ikakhulu kwizihlanganisi ezahlukeneyo kwindawo yokungena nokuphuma kwemibhobho yecompressor.Umlinganiselo wokuvuza wahlulwe ngokubanzi ngokobungakanani bokuvula ukuvuza, i-flange kunye nabanyeOko kukuthi, ukuvuza kwemibhobho yerhasi yendalo ngokuqhelekileyo kukuvuza kwe-orifice, kwaye inkqubo yokuvuza inokuthathwa njengokuphuma kwerhasi ecinezelekayo.Ukusuka kuphando lwengozi, Ukuba nokwenzeka kwengozi yokuvuza encinci (umngxuma omncinci) inkulu kwaye isikhulu (umngxuma omkhulu) ingozi yokuvuza ayinakwenzeka.Ngapha koko, kwimeko yokuvuza okukhulu kombhobho werhasi yendalo, irhasi yendalo evuzayo iya kukhawuleza igcwalise isithuba segumbi elipheleleyo lecompressor, kwaye umtshina werhasi etshayo unokufunyanwa ngokufanelekileyo nakweyiphi na indawo.Ngoko ke, ukuvuza okuncinci kuphela kufuneka kuthathelwe ingqalelo ukulungiselela i-detector yegesi evuthayo.Apha, indawo yokuvuza ithathwa njenge-1 Umngxuma omncinci ngokwaneleyo ukuphatha umbhobho njengesitya esikhulu ngokwaneleyo.Ngoko ke, uxinzelelo kwipayipi aluyi kutshintsha phantsi kweempembelelo zokuvuza, oko kukuthi, ukuvuza kwe-isobaric.

1. Imeko yokuvuza kwerhasi etshayo kwindawo ekungangeni moya kuyo kakuhle

Kwindawo evaliweyo, Ngenxa yokungangeni komoya okulambathayo (okunokuqondwa njengendawo yomoya omileyo), irhasi yendalo itshizwa ukusuka kwindawo evuzayo kwindawo yoxinzelelo oluphezulu kunye noxinzelelo oluphezulu, kukho umahluko omkhulu woxinzelelo kunye nemeko engqongileyo, kunye ne-vortices yendawo iveliswa ukuba yenze "indawo yokucima", kwaye igesi ejikelezileyo iya kuhamba ngokuthe tye kwi-jet boundary layer ukwenza "indawo ye-vacuum" Uxinzelelo oluphantsi olubangelwayo luya kulungelelanisa kunye nokusingqongileyo ngexesha elifutshane kakhulu kwaye kuluhlu oluncinci kakhulu, xuba kunye neendaba ezijikelezileyo, kwaye ngokuqhubekayo usasazeke kwi-atmosfera, ngaloo ndlela wenze ifom ye-diffusion yamahhala, kunye nokugxininiswa kunye nokuhanjiswa kwesantya ngokusisiseko ku-symmetrical.

Ekubeni ubunzima bemolekyuli begesi yendalo bumalunga ne-16, i-Avareji yobunzima bemolekyuli yomoya ongonelanga (29) 60%, irhasi yendalo evuzayo iya kuchaphazeleka ngokunyuka okuthe nkqo phezulu emoyeni.Kwindawo engekude ne-orifice yokuvuza, isantya sokuqala sidlala indima enkulu, kwaye iimpawu zayo zokuhamba zifana nejethi ecocekileyo, eyona nto ayichaphazeleki ngumoya.Ngokunyuka komgama we-injection, ububanzi be-jet bukhula ngokuthe ngcembe kwaye indawo yokusabalalisa inyuka ngokuthe ngcembe ngenxa yokunyanzeliswa kwezinto ezijikelezayo endleleni Isiphumo sokuthintela ulwelo olusisigxina kunye nefuthe lokuqala lokukhawuleza liyancipha ngokuthe ngcembe.Ngokuchasene noko, i-buoyancy effect ibonakala ngokuthe ngcembe kwaye ekugqibeleni ithatha isikhundla esiphezulu.Iqondo lokusasazwa simahla kwerhasi yendalo liyenyuka.Ukuphakama kwentshukumo yokugqibela kunokufikelela phezulu kwendawo yengingqi, kwaye imeko yayo yokuvuza ngokuqhelekileyo ngamafu amakhowa.Ukuba indawo yokuvuza ingaphezulu kombhobho kwaye ijethi ime nkqo ukuya phezulu, iya kuba yi-engile yokubeka iliso efileyo ngaphakathi komphakamo othile ukusuka kumgama othe tye kwindawo yokuvuza.Ngapha koko, nokuba kwicala elithe nkqo okanye elithe tye, kunye nokwandiswa komgama wokusasazwa, ukuxinana kwerhasi yendalo kuya kuncipha, nangaphantsi kwe-25 yomda ophantsi woqhushumbo, kwaye ukufunyanwa kwegesi etshayo kunye nenkqubo ye-alam ayiyi kuqalisa.

Kwelinye icala, irhasi yendalo evuzayo iya kuthi ekugqibeleni ihambe iye phezulu kwindawo phantsi kwesenzo sobuoyancy.Ngeli xesha, ngenxa yokuba umphezulu wendawo yindawo evaliweyo, igesi yendalo evuzayo iya kuqhubeka iqokelelana phezulu, kwaye ide ifikelele kumda wokuqhuma.

2. Uphahla olunyanzeliswayo lokukhupha iimeko zokuvuza kwerhasi enokutsha

Ngokusekwe ku-1 uhlalutyo lokuvuza kwegesi enokutsha kwindawo engenamoya, xa isixhobo sokukhupha sibekwe phezulu kwigumbi loxinzelelo, nokuba sisongezelelo somoya wendalo okanye isongezelelo somoya ngoomatshini, imeko yokuhamba komoya kwisityalo iya kutshintsha, kwaye ijethi yegesi yendalo evuzayo iya kuphambuka iye kwindawo ethe nkqo kwindawo yokuphuma.Njengoko umkhombandlela wokuhamba komoya uphezulu ngokubanzi, irhasi yendalo evuzayo ayinyuswanga kuphela ngokunyuka komoya, kodwa ikwanyanzelwa kukunyuka komoya ukuya phezulu.Isantya sentshukumo esiya phezulu siya kukhawuleziswa, umgama othe tyaba wokusasazwa uya kucuthwa, kwaye indawo yokubeka iliso efileyo iya kwandiswa.Ngakolunye uhlangothi, ngenxa yokunyuka kokunyuka kokunyuka, izinga lokunciphisa i-concentration yegesi yendalo liya kwanda.Ukuba ukuvuza akwanele ukugcina ugxininiso olwaneleyo, xa indawo yokufakela i-detector yegesi evuthayo iphezulu, ukufumanisa kunye nenkqubo ye-alamu ayiyi kuqala.
