I-Geyser phenomenon

I-Geyser phenomenon ibhekisela esimweni sokuqhuma okubangelwa uketshezi lwe-cryogenic oluhanjiswa phansi ngepayipi elide eliqondile (kubhekisela esilinganisweni sobude bobubanzi obufinyelela inani elithile) ngenxa yamabhamuza akhiqizwa ukuhwamuka koketshezi, kanye ne-polymerization phakathi kwamabhamuza. kuzokwenzeka ngokwanda kwamabhamuza, futhi ekugcineni uketshezi lwe-cryogenic luzohlehliswa luphume emnyango wepayipi.

Amagiza angase enzeka uma izinga lokugeleza epayipini liphansi, kodwa adinga ukuqashelwa kuphela uma ukugeleza kuma.

Uma uketshezi lwe-cryogenic lugeleza phansi epayipini eliqondile, kufana nenqubo yokupholisa kuqala. I-Cryogenic liquid izobilisa futhi ihwamuke ngenxa yokushisa, okuhlukile kunqubo yokupholisa kuqala! Nokho, ukushisa kuvela ngokuyinhloko ekuhlaseleni okuncane kokushisa okuzungezile, esikhundleni somthamo wokushisa wesistimu omkhulu kunqubo yokupholisa kwangaphambili. Ngakho-ke, ungqimba lomngcele we-liquid olunezinga lokushisa eliphakeme kakhulu lakhiwa eduze kodonga lwe-tube, kunefilimu ye-vapor. Lapho uketshezi lugeleza epayipini eliqondile, ngenxa yokuhlasela kokushisa kwemvelo, ukuminyana okushisayo kwesendlalelo somngcele wamanzi eduze kodonga lwamapayipi kuncipha. Ngaphansi kwesenzo se-buoyancy, uketshezi luzohlehlisa ukugeleza okuya phezulu, kwenze isendlalelo somngcele woketshezi olushisayo, kuyilapho uketshezi olubandayo oluphakathi nendawo lugeleza luye phansi, lwenza umphumela wokuguquguquka phakathi kwakho kokubili. Isendlalelo somngcele woketshezi olushisayo lujiya kancane kancane lugudle isiqondiso se-mainstream luze luvimbe ngokuphelele uketshezi oluphakathi nendawo futhi lumise ukugeleza. Ngemva kwalokho, ngenxa yokuthi ayikho i-convection yokususa ukushisa, izinga lokushisa loketshezi endaweni eshisayo likhuphuka ngokushesha. Ngemuva kokuthi izinga lokushisa loketshezi lifinyelela izinga lokushisa lokugcwala, liqala ukubilisa futhi likhiqize amabhamuza Ibhomu legesi elizingile libambezela ukukhuphuka kwamabhamuza.

Ngenxa yokuba khona kwamabhamuza epayipini elime mpo, ukusabela kwamandla e-bubble shear viscous kuzonciphisa ukucindezela okumile phansi kwebhamuza, okuzokwenza uketshezi olusele lushise ngokweqile, ngaleyo ndlela kukhiqizwe umhwamuko owengeziwe, wona nawo uzowushisa kakhulu. yenza ingcindezi emile ibe phansi, ngakho-ke ukukhuthazana, ngezinga elithile, kuzokhiqiza umhwamuko omningi. Ukwenzeka kwe-geyser, ethi ayifane nokuqhuma, kwenzeka lapho uketshezi, oluphethe ukukhanya kwesitimu, lubuyela epayipini. Inani elithile lomhwamuko elilandelwa uketshezi olukhishelwe endaweni engaphezulu yethangi lizodala izinguquko ezimangalisayo kuzinga lokushisa eliphelele lesikhala sethangi, okuholela ekushintsheni okukhulu kwengcindezi. Lapho ukuguquguquka kwengcindezi kusezingeni eliphakeme kanye nesigodi sokucindezela, kungenzeka ukwenza ithangi libe sesimweni sokucindezela okubi. Umthelela womehluko wengcindezi uzoholela ekulimaleni kwesakhiwo sohlelo.

Ngemva kokuqhuma komhwamuko, ukucindezela kwepayipi kwehla ngokushesha, futhi uketshezi lwe-cryogenic luphinde lufakwe epayipini eliqondile ngenxa yomphumela wamandla adonsela phansi. Uketshezi olunesivinini esikhulu luzoveza ukushaqeka kokucindezela okufana nesando samanzi, okunomthelela omkhulu ohlelweni, ikakhulukazi emishinini yasemkhathini.

Ukuze kuqedwe noma kuncishiswe umonakalo odalwe yisimo se-geyser, ekufakweni, ngakolunye uhlangothi, kufanele sinake ukufakwa kwesistimu yamapayipi, ngoba ukuhlasela kokushisa kuyimbangela eyinhloko ye-geyser phenomenon; Ngakolunye uhlangothi, amasu amaningana angacutshungulwa: umjovo wegesi enganciphisi inert, umjovo owengeziwe we-cryogenic liquid kanye nepayipi lokujikeleza. Ingqikithi yalezi zinhlelo ukudlulisa ukushisa okweqile koketshezi lwe-cryogenic, ukugwema ukunqwabelana kokushisa okudlulele, ukuze kuvinjwe ukuvela kwesimo se-geyser.

Ohlelweni lomjovo wegesi engasebenzi, i-helium ivamise ukusetshenziswa njengegesi engasebenzi, futhi i-helium ijovwa ngaphansi kwepayipi. Umehluko we-vapor pressure phakathi kwe-liquid ne-helium ungasetshenziswa ukwenza ukudluliswa okukhulu komhwamuko womkhiqizo usuka oketshezini uye ku-helium mass, ukuze kuhwamuke ingxenye yoketshezi lwe-cryogenic, ukumunca ukushisa oketshezini lwe-cryogenic, futhi kukhiqizwe umphumela wokupholisa ngokweqile, ngaleyo ndlela kuvimbele ukunqwabelana koketshezi oluningi. ukushisa. Lolu hlelo lusetshenziswa kwezinye izinhlelo zokugcwaliswa kwe-space propellant. Ukugcwaliswa okungeziwe ukunciphisa izinga lokushisa loketshezi lwe-cryogenic ngokungeza uketshezi lwe-cryogenic olupholile kakhulu, kanti uhlelo lokwengeza ipayipi lokujikeleza kuwukusungula isimo semvelo sokujikeleza phakathi kwepayipi nethangi ngokungeza ipayipi, ukuze kudluliselwe ukushisa okweqile ezindaweni zendawo futhi kucekele phansi ipayipi. izimo zokuphehla amagiza.

Kubhekwe esihlokweni esilandelayo ukuze uthole eminye imibuzo!
