He aha te take me whakaheke te mamaoa wera rawa ki te mamaoa kukū?

01. Te mamaoa kuhu
Ka whakamahana te wai ki te koropuputanga i raro i tetahi pehanga, ka timata te wai ki te kohu, ka huri haere hei mamaoa.I tenei wa, ko te pāmahana mamaoa ko te pāmahana waiwai, e kiia nei ko "te korohu kukū".Ko te ahua o te mamaoa kukū pai e pa ana ki te hononga kotahi-ki-tetahi i waenga i te pāmahana, te pehanga me te kiato mamaoa.

02. Te mamaoa wera rawa
I te wa e wera tonu ana te mamaoa kukū, ka piki ake te pāmahana me te neke atu i te pāmahana waiwai i raro i tenei pehanga, ka riro te mamaoa hei "mamao wera nui" me tetahi tohu o te wera nui.I tenei wa, ko te pehanga, te mahana, me te kiato karekau he reta kotahi-ki-tetahi.Mena kei te noho tonu te ine i runga i te mamaoa kukū, ka nui ake te hapa.

I roto i nga mahi whakangao, ko te nuinga o nga kaiwhakamahi ka kowhiri ki te whakamahi i nga tipu hiko waiariki mo te whakamahana i waenga.Ko te mamaoa wera nui i hangaia e te tipu hiko he teitei-te wera me te pehanga teitei.Me haere i roto i te punaha teihana whakamahana me te whakaheke pehanga ki te huri i te mamaoa wera nui ki roto i te tima kukū i mua i te haria atu ki Mo nga kaiwhakamahi, ka taea anake e te mamaoa wera te tuku i te wera tino whaihua ina whakamatao ki te ahua kukū.

I muri i te kawe i te mamaoa wera nui, i te mea ka huri nga tikanga mahi (penei i te pāmahana me te pehanga), i te mea kaore i te teitei te tohu o te wera nui, ka heke te pāmahana na te ngaronga o te wera, ka uru ki roto i te ahua kukū, supersaturated ranei. he ahua tino wera, ka huri.ka noho mamaoa kukū.

He aha te take me whakaheke te mamaoa wera rawa ki te mamaoa kukū?
1.Me whakamatao te mamaoa tino wera ki te pāmahana waiwai i mua i te tukunga o te enthalpy whakaetonga.He iti rawa te wera i tukuna mai i te whakamahana mamaoa wera nui ki te pāmahana waiwai ka whakaritea ki te enthalpy whakaetonga.Mena he iti te wera nui o te mamaoa, he ngawari te tuku o tenei wahanga o te wera, engari ki te nui te wera nui, ka roa te wa whakamatao, a he iti noa te waahi o te wera ka taea te tuku i taua wa.Ina whakaritea ki te enthalpy whakaetonga o te mamaoa kukū, he iti rawa te wera i tukuna e te mamaoa wera i te whakamataonga ki te pāmahana waiwai, ka iti te mahi o nga taputapu whakaputa.

2.He rereke i te mamaoa kukū, kaore i te tino mohio te pāmahana o te mamaoa wera.Ko te mamaoa wera nui me whakamatao i mua i te tuku wera, engari ko te mamaoa kukū ka tukuna noa te wera ma te huringa wahanga.Ka tukuna te wera o te wera wera, ka puta he pāmahana i roto i nga taputapu whakawhiti wera.rōnaki.Ko te mea nui i roto i te whakaputanga ko te pumau o te pāmahana mamaoa.Ko te pumau o te korowha he pai ki te whakahaere whakamahana, na te mea ko te whakawhitinga wera te nuinga e whakawhirinaki ana ki te rereketanga o te wera i waenga i te mamaoa me te mahana, a he uaua ki te pumau te wera o te mamaoa wera, kaore i te pai ki te whakahaere whakamahana.

3.Ahakoa he teitei ake te mahana o te mamaoa wera i raro i te pehanga kotahi i tera o te mamaoa kukū, he iti ake tona kaha whakawhiti wera i to te mamaoa kukū.No reira, he iti ake te kaha o te mamaoa wera nui atu i tera o te mamaoa kukū i te wa e whakawhiti wera ana i te pehanga kotahi.

No reira, i te wa e whakahaerea ana nga taputapu, ko nga painga o te huri i te tima superheated ki roto i te tima kukū na roto i te desuperheater ka nui ake i nga huakore.Ko ona painga ka taea te whakariterite penei:

He tiketike te whakarea whakawhiti wera o te mamaoa kukū.I te wa o te whakamaaramatanga, he teitei ake te whakarea o te wera o te werawera o te mamaoa wera ma te "whakawhitinga-wera-whakawera-te-te-te-te-te-te-te-te-te-te-te-te-te-te-te-te-te-te-whakamaeke".

Na te iti o te pāmahana, he maha hoki nga painga o te mamaoa kukū mo te mahi taputapu.Ka taea e ia te whakaora i te mamaoa me te tino painga ki te whakaiti i te kohi mamaoa.Ko te tikanga, ka whakamahia te mamaoa kukū mo te whakawhiti wera i roto i te hanga matū.
