Izinhlobo ukudluliswa ukushisa: ukudluliswa ukushisa Coefficient

Noma yimuphi kulomzimba sinezici ezifana ukushisa, ezingasetshenziswa ukwandisa bese wehlise. Ukushisa akuyona izidakamizwa impahla: njengengxenye bamandla alo angaphakathi, kwenzeka ngenxa ukunyakaza kanye nokuxhumana zishintshe. Njengoba ukushisa izinto ezihlukahlukene zingase zingafani, kukhona inqubo ukudluliswa ukushisa kusukela into eliwu into ngemadlana encane ukushisa. Le nqubo ibizwa ngokuthi ukudluliswa ukushisa. Izinhlobo ezinkulu ukudluliswa ukushisa, kanye nezindlela zabo luzoqaliswa okuxoxwe ngazo kulesi sihloko.

Ukunqunywa ezishisayo

Heat exchange noma ukudlulisa inqubo lokushisa kungathatha indawo ngaphakathi ndaba, futhi kusukela unesimo kwenye. Kulesi umfutho ukushisa ixhomeke Izakhiwo sendaba, izinga lokushisa kwe-izinto (uma ukushisa exchange ezihilela izinto eziningana) kanye nemithetho ye physics. Heat ukudluliswa - kuyinqubo njalo kwenzeka unilaterally. Isimiso eyinhloko ukushisa exchange wukuthi umzimba evuthayo kakhulu njalo unika shisisa into nge lokushisa aphansi. Ngokwesibonelo, ngensimbi eshisayo liletha ukutjhisa lapho izingubo ayina ibhulukwe, hhayi okuphambene nalokho. ukudluliselwa Heat - into kuye Inkomba sikhathi, okuyinto ephawula engelapheki ukushisa ukusatshalaliswa emkhathini.

izindlela zokudlulisa ukushisa

Izindlela zika ukuxhumana ezishisayo of izinto zingase zithole ezihlukile. Kukhona izinhlobo ezintathu ukudluliswa ukushisa ngokwemvelo:

1. conductivity ezishisayo - indlela aphakathi lokudluliselwa ukushisa komunye umzimba okuyingxenye kwenye, noma kwenye into. Impahla esekelwe inhomogeneities lokushisa kulezi izinto.
2. Ukubika Inkinga YeWindows - ukushisa exchange phakathi uketshezi (ewuketshezi, umoya).
3. Kushisa bhé kule ndawo umphumela - ukudluliswa kwezinga lokushisa okusuka evuthayo kanye evuthayo ngezithukuthuku zabo imizimba amandla (imithombo) ngesimo amagagasi kagesi nge spectrum njalo.

Cabangela izinhlobo ababaliweyo ukudluliswa ukushisa kabanzi.

conductivity ezishisayo

Ngokuvamile, conductivity ezishisayo is ebonwe ukudla okuqinile. Uma ngaphansi kwethonya yimuphi isici kwelinye futhi athi unesimo esifana avele ezindaweni okushisa ahlukene, amandla ezishisayo wesabelo evuthayo sizowela amakhaza. Isenzakalo esifanayo kwezinye izimo kungabonakala nasemkhakheni ongaboni. Isibonelo, uma uthatha induku yensimbi, isibonelo, inaliti, futhi shisisa emlilweni, khona-ke emva kwesikhashana, ubone indlela energy ezishisayo idluliselwa ngokusebenzisa inaliti ukwakha ezindaweni ezithile siyakhazimula. Endaweni lapho izinga lokushisa ephakeme ziyavutha licace, futhi Ngakolunye uhlangothi, lapho t ingaphansi ke mnyama. I conductivity ezishisayo kungabuye waphawula phakathi izindikimba ezimbili (mug yetiye elishisayo futhi isandla)

Amandla ukudluliswa ukushisa ukugeleza kuxhomeke ezicini eziningi, isilinganiso okuyinto sezibalo French Fourier kwembulwe. Lezi zinto zibandakanya izinga lokushisa umyela lokuqala (isilinganiso umehluko lokushisa enisemikhawulweni induku ibanga ukusuka komunye umkhawulo kuya komunye), esiphambanweni kwesigaba izingxenye zomzimba, kanye conductivity ezishisayo (zonke izinto-ke ihlukile, kodwa aphakeme ebonwe izinsimbi). Coefficient esiphawuleka kunazo zonke conductivity ezishisayo okuqhubekisela ikhopha ne-aluminiyamu. Akumangazi ukuthi lezi zinsimbi amabili avame ukusetshenziswa ekwenzeni izintambo kagesi. Ukulandela Fourier umthetho ukushisa ukugeleza ubuningi zingandiswa noma kwehle ngokushintsha enye yalezi nemingcele.

Ukubika Inkinga YeWindows ukudluliswa ukushisa izinhlobo

Ukubika Inkinga YeWindows esingokwemvelo ikakhulukazi ngoba amagesi futhi uketshezi, has izingxenye ezimbili: conductivity ezishisayo kanye nokunyakaza aphakathi (ukusatshalaliswa) of the medium. Ukubika Inkinga YeWindows mshini wezenzo simiswe ngalendlela lelandzelako: ukwanda lokushisa uketshezi izidakamizwa molecule uqale ezinyakazayo yayo futhi bakhuthele kakhulu ngokungabi bikho ngekwendzawo izingqinamba izidakamizwa umthamo iyakhula. Ngenxa yalo inqubo uzokwehla kwabantu into futhi ukuhamba kwayo phezulu. Isibonelo esimangalisayo Ukubika Inkinga YeWindows - ukuhamba evuthayo emoyeni cooler kusukela ibhethri ophahleni.

Hlukanisa khulula futhi ziphoqelelwe Ukubika Inkinga YeWindows ukushisa ukudluliselwa izinhlobo. Ukushisa kanye ukuyaluza khulula mass uhlobo kungenxa inhomogeneity lomcebo, isb ashisayo ketshezi liyaphuma phezu abandayo indlela yemvelo ngaphandle linalo ithonya amabutho yangaphandle (isb, nge Ukushisa Igumbi zokufudumeza). Lapho ophoqelelwe Ukubika Inkinga YeWindows mass ukunyakaza kwenzeka ngaphansi isenzo amabutho angaphandle, ezifana ibangele itiye spoon.

ukushisa ekhazimulayo

Kushisa bhé kule ndawo noma ekhazimulayo ukudluliswa ukushisa kungathatha indawo ngaphandle contact nomunye into noma into, ngakho-ke kungenzeka ngisho a cleaner (cleaner). Radiative ukushisa ukudluliselwa umuntu azalwa nalo lokuhlaziya yonke imigwamanda ngokwezinga elikhulu noma elincane, futhi livela ngesimo amagagasi kagesi nge spectrum okuqhubekayo. Isibonelo esimangalisayo - imisebe yelanga. Lo mshini wezenzo simiswe ngalendlela lelandzelako: umzimba njalo likhipha ethile ukushisa esikhaleni nxazonke. Lapho le energy uthola omunye into noma into, abanye it is amuncwa ingxenye yesibili sidlula, kanti eyesithathu kubonakala imvelo. Iyiphi into kungaba kokubili ezishisa kakhulu zikhipha izinhlayiyana ukushisa futhi ulalele, indaba amnyama ukwazi mba ukushisa ezingaphezu kuka ukukhanya.

Kuhlanganiswe ukudluliswa ukushisa izindlela

Emvelweni, izinhlobo izinqubo zokudlulisa ukushisa kuyaqabukela zenzeka atihambi todvwa. Ngokuvamile, kungabonwa ndawonye. Ngo wokushintsha kwamandla nokwakheka kwezinto, inhlanganisela ngisho abe negama, isibonelo, ezishisayo conductivity + Ukubika Inkinga YeWindows - ukudluliswa convective ukushisa futhi ezishisayo conductivity + emisebeni ezishisayo libizwa ngemisebe-conductive ukudluliswa ukushisa. Ngaphezu kwalokho, lezi zinhlobo engayodwa kuhlangene ukushisa njengoba:

• ukudluliselwa Heat - ukushisa ukunyakaza phakathi igesi, nempahla okuluketshezi noma okuqinile.
• ukudluliselwa Heat - ukudluliselwa t komunye ndaba kwenye ngokusebenzisa isimiso lokukhanda.
• kwakhiwa ukudluliswa ukushisa Convective-radiative is by inhlanganisela Ukubika Inkinga YeWindows nemisebe ezishisayo.

Izinhlobo ukushisa exchange ngokwemvelo (izibonelo)

ukudluliselwa Heat ngokwemvelo kudlala indima enkulu futhi akugcini amalahle elangeni wonke. Enkulukazi Ukubika Inkinga YeWindows imisinga, ezifana ukuhamba emoyeni uquqaba, zinquma sezulu yonke iplanethi yethu.

I conductivity ezishisayo of core yomhlaba kuholela ziqhuma iziphethu namadwala mlilo. Lena kuphela ingxenye encane izibonelo exchange ukushisa embulungeni yonke. Bebonke bakha eziwuhlobo convective ukushisa ukudluliselwa nemisebe ukudluliswa ukushisa izinhlobo conductive kudingekile ekuphileni emhlabeni.

Ukusetshenziswa ukushisa emisebenzini anthropological

Heat - kuyingxenye ebalulekile cishe zonke izinqubo zezimboni. Kunzima ukusho onjani ukushisa lwabantu kakhulu emnothweni kazwelonke. Mhlawumbe wonke ezintathu ngesikhathi esisodwa. Ngenxa inqubo yokudlulisa ukushisa kwenzeka sokuncibilikisa izinsimbi, ukukhiqizwa omningi izimpahla, eziqala izinto ukusetshenziswa nsuku zonke ziphethe isikhala imikhumbi.

Ibalulekile impucuko ube amayunithi ezishisayo olukwazi ukushintsha energy ezishisayo ku amandla ezisebenzisekayo. Lezi zihlanganisa uphethiloli, udizili, compressor, ukufakwa ophephela. Ukuze umsebenzi wabo basebenzisa izinhlobo ezahlukene zokudlulisa ukushisa.
