Uhlalutyo lweempawu zokusetyenziswa kwezitena ezingena umoya

Uhlobo olutsha lwezitena ezisasaza umoya alunako ukuvelisa ukunganyamezeleki okungaphantsi okanye into engathandekiyo yesitena sokuqala somoya esinezitena ngenxa yeempawu zobume bezinto ezincinci. Xa isitena esingena umoya sisebenza kwaye singena umoya, umoya obandayo uhamba kwislit ukuze uvelise ubushushu obukhulu, kwaye olunye uxinzelelo lwe-thermal olwenziweyo luya kugxila kufutshane nesikwere, ngakumbi uxinzelelo lwe-thermal kwindawo yokuphuma komoya inkulu, isenza uqhekeko kwiinguqu zotshintsho ngexesha lokusetyenziswa, nto leyo ebangela ukuba intsimbi etyhidiweyo ingene ngokulula kwisikroba ukwenza ukunganyamezeleki okungaphantsi okanye into engathandekiyo. Ukongeza, ukuba ivalve esezantsi evaliweyo ivalwa ngokukhawuleza esiphelweni, intsimbi etyhidiweyo iya kungena kwisikwere ngoxinzelelo oluqinisekileyo, ke kuyimfuneko ukufakela i-valve yokumitha engafakwanga kumbhobho we-argon.

Ke ngoko, uqhekezo lohlobo lwezitena ezivumayo zomoya kufuneka lube nobungakanani obufanelekileyo kunye nobuzinzileyo bokuhamba komoya kunye nezinto ezinokuzinza okuhle kokushisa ukuze kuncitshiswe intsimbi. Ijelo elingenayo umoya lezitena ezisasaza umoya linani elikhulu lezinto ezibonakalayo ezidityanisiweyo ezisasazeke kumzimba wezitena (njengoko kubonisiwe kumzobo 2). Ezi micron-scale scortuous channels zenza ukunganyangeki okukhulu ekungeneni kwentsimbi etyhidiweyo, kwaye azinakungena ekusetyenzisweni kwayo. , Amaqamza omoya aveliswe zizitena zomoya ezivumayo ezisasazekayo zincinci, ziyalingana kwaye zixinene, kulula ukuvusa isinyithi esinyibilikileyo kubushushu obufanayo, kwaye kulula ukukhuthaza ukudada kwe-inclusions ukufezekisa eyona nto ibalaseleyo.

Isitena esitsha esinokusasazeka ngumoya akukho lula ukubangela ukuba icandelo lesitena liwele. Xa uvuthela i-argon, indawo yokuphuma komoya yohlobo lwezitena ezingena ngaphakathi emoyeni ichukumiseka ngokuthe ngqo ngobushushu obuphezulu bentsimbi etyibilikayo kunye nokuhamba komoya obandayo ngokuqhubekayo kuphuma, kukhokelela kwithambeka lobushushu elikhulu. Uxinzelelo olushushu kwindawo yokuphuma komoya eyenza islit inkulu kakhulu. Ngexesha lenkqubo, ukufudumeza okukhawulezayo kunye nengqele kuya kubangela ukunqamleza kufutshane nendawo yokuphuma yomoya, eya kuthi ibangele ukuba isikhafu sihambe kwaye senze ezantsi ukuvuthela kungene. Uxinzelelo lwe-thermal olubangelwa kukuwa kweqondo lobushushu kunye nokwanda kwevolumetric kwezinye iindawo kunokwenza ngokulula isitena somoya esine-permeable ukuvelisa icandelo elinqamlezileyo, elibeka phambili iimfuno eziphezulu zokunganyangeki kukothuka kwezinto ezinqabileyo. Nangona kunjalo, kukho imijelo yegesi yemicron kuwo wonke umphezulu womsebenzi wesitena esivelisayo, kwaye iqondo lobushushu bomgangatho osebenzayo lincinci, ukuze isitena esitsha esingena lula akukho lula ukuvelisa icandelo eliphambili lobume bezitena.
