Ukuhlangana

La ukuhlangana Kuyinqubo eyenzeka emvelweni lapho ukushisa kudluliselwa khona phakathi kwezinto eziwuketshezi, igesi noma uketshezi olunoketshezi, oluqinile noluketshezi, njll. Zonke lezi zinhlanganisela zingenzeka uma sikhuluma ngale nqubo yokushintshanisa ukushisa lapho yomibili imizimba, kungakhathaliseki isimo sayo, izoba namazinga okushisa ahlukene. I-Convection iyinqubo ebalulekile ku-meteorology ebandakanya ukudluliswa kokushisa phakathi kwezindimbane zomoya. Uma ufuna ukufunda ngalezi zehlakalo zomkhathi, ungase futhi ube nentshisekelo olwazini mayelana imibukiso ye-convection futhi mayelana isimo sezulu esibandayo nokushisa.

Ngabe ufuna ukwazi kabanzi nge-convection? Kulesi sihloko sizochaza konke ngakho.

Ukudluliswa kokushisa

Ukudluliswa kokushisa kuyinto eyinhloko ekuhambiseni izinto. Akunandaba nesimo somzimba ngamunye, Inqobo nje uma kukhona umehluko obonakalayo wokushisa, ukuhanjiswa kungenzeka. Le yinqubo esiyisebenzisayo ukushisa amanzi ngembiza. Lapho imizimba emibili emazingeni okushisa ahlukene ihlangana, esikwaziyo njengokugeleza kokushisa kwenzeka. Kungumzimba onezinga lokushisa eliphakeme okudlulisa ukushisa kube kuncane.

Lesi ngesinye sezizathu esenza ukuthi, lapho sibeka isandla sethu eduze kwesitofu, sizwe ukushisa. Isitofu asidlulisi lokho kushisa. Kukhona nezinye izinqubo zokudlulisa ukushisa ezifana nemisebe kanye nokuqhuba okuchazwe ngokuhlangana ne-convection, ngakho-ke sizophinde sibuyekeze ngokuhamba kwesikhathi.

Kokubili uketshezi namagesi kubhekwa njengoketshezi. Ukunyakaza kwama-molecule awo kunesibopho sokuthi ukushisa kukwazi ukusungula ukugeleza phakathi kwemizimba emibili. Ukungahambi kahle kwe-thermal kusho ukuthi isisindo kufanele siphoqeleke ukukhipha noma ukukhipha ukushisa. Ukwenza lokhu, iyapholisa noma ishise okuqinile noma okuwuketshezi. Lesi simiso siyisisekelo sokuqonda ukuthi izenzakalo ezifana nalezi ukwakheka kwesishingishane nokuthi kanjani amagagasi okushisa ayathinta.

I-heater isetshenziswa kuma-boilers. Lokhu kuqukethe ipayipi lensimbi elinamanzi ajikelezayo ngaphakathi. Ngaphandle sizoba negesi emazingeni okushisa aphezulu kakhulu. Ngenqubo ye-convection, igesi izokwazi ukudlulisa ukushisa kwayo ku-tube yensimbi futhi amanzi azoyithola ngokuqhutshwa. Ishubhu liyashisa futhi lidlulisela ukushisa emanzini ageleza kwenye indawo. Lawa manzi, lapho ethola ukushisa nge-convection, ayashisa aze aphenduke isitimu. Ungafunda kabanzi mayelana nobudlelwano phakathi kokushisa nezinga lokushisa kulesi sixhumanisi: ubudlelwano phakathi kokushisa nezinga lokushisa.

Ukushayela

Esinye sezihloko ezivame ukuxoxwa uma kukhulunywa ngamandla kungukudluliswa kokushisa okuqondile nokungaqondile. Emishini kagesi yasendlini sisebenzisa ukufudumeza nomoya opholisa ukudlulisa ukushisa noma amakhaza. Le mishini nayo ilahlekelwa amandla ayo. Umhlaba jikelele phakathi kwenani lamandla esiwasebenzisayo nalawo esiwalahlayo ifanelekela ukusebenza kahle kwamandla futhi kuyinto eguquguqukayo ebalulekile okufanele uyinake enanini lokugcina lomkhiqizo.

Ukushayela kuyinqubo eqondakala kalula yiwo wonke umuntu. Ingabe mayelana ukudluliswa kokushisa phakathi kwamaphoyinti amabili asezingeni lokushisa elihlukile. Lokhu kudlulisa kwenzeka ngaphandle kokushintshana kwendaba phakathi kwabo. Isibonelo esilula siwukuthi: sinebha yensimbi enomkhawulo owodwa kuma-degree angu-80 kanti enye ekamelweni lokushisa. Uma lingekho elinye ithonya langaphandle, ukudluliswa kokushisa kuzokwenzeka ngokuqhutshwa kusukela ekugcineni okushisayo kuya ekugcineni okubandayo. Lokhu kuzodala ukuthi ukuphela okubandayo kugcine kufudumele. Akudingekile ukusho ukuthi, ukuqhuba kuncike ngokuphelele ohlotsheni lwendaba esikhuluma ngayo. Akufani nokukhuluma ngensimbi njengoba kukhulunywa ngokhuni. I-Conductivity iyisici okufanele sinakwe kule nqubo ebonakalayo yokushintshisana kwamandla.

Imisebe

Enye inqubo ukushintshaniswa kokushisa yimisebe. Sisebenzisa futhi kakhulu ekhaya. Ngukushisa okukhishwa ngumzimba ngenxa yezinga lokushisa kodwa ngaphandle kokuthintana phakathi kwemizimba. Sibonile ukuthi lapho kuqhutshwa kufanele kube nokungqubuzana phakathi kwemizimba noma ukwandiswa kokushisa emzimbeni ofanayo. Okungeke kube nakho ukushintshaniswa kwezindaba. Kulokhu, umzimba ofudumele ungafudumeza amakhaza ngaphandle kokuwuthinta.

Kulolu hlobo lwenqubo sizobona ukushintshana ngokushisa nge iqiniso elilula lokuthi umzimba uyashisa kunomunye. Ukuze le nqubo ibonakale, umzimba oshisa kakhulu kufanele ube ezingeni lokushisa eliphezulu kakhulu. Isibonelo esilula salokhu singabonakala ehlobo lapho uya ogwini. Uma ushiya imoto yakho imile bese kudlula amahora, ubuyela emuva ukuyolanda okuthile futhi uma uthinta izinsimbi zezicabha uyasha ngoba kushisa kakhulu. ILanga likude kakhulu, nokho liyakwazi ukudlulisa ukushisa emotweni ngemisebe. Kuyathakazelisa futhi ukwazi ukuthi lokhu kuhlobana kanjani nezimo zezulu, njengamafu ohlobo i-cumulonimbus nokuthi kanjani amagagasi okushisa kungaba nomthelela kula mafu.

Endabeni yemisebe sibheka nohlobo lwezinto esibhekene nazo. Ingaphezulu lamapulangwe liyashisa kepha alikwazi ukugcina ukushisa okungako ngenxa yempahla yalo evikela.

Izinhlobo zokudlulisa

Lapho sesichazile ukudluliswa kokushisa okungenzeka okukhona, sizobala izinhlobo ze-convection ezikhona. Ukudluliswa kokushisa nge-convection kungenzeka ngezindlela eziningi futhi kuyilezi:

• Kuphoqiwe: Kwenziwa ngefeni, esimweni somoya, noma ipompo, esimweni samanzi, lapho uketshezi ludlula endaweni eshisayo bese ukushisa kuyiswa endaweni ebandayo.
• Natural: kwenzeka lapho uketshezi lukhipha ukushisa endaweni eshisayo futhi luguqula ubukhulu balo. Lokhu kudala ukuthi iye endaweni ebanda kakhulu lapho izodela khona ukushisa kwayo.

Ukuze uqonde kangcono izinhlobo ezahlukene ze-convection, ake sinikeze isibonelo. Uma sivula i-radiator, kufanele silinde izinga lokushisa likhuphuke. Uma sibeka isandla sethu phezu kwe-radiator ebangeni elifushane, sizobona ukuthi kukhona ukugeleza komoya okungokwemvelo ngokuphelele, njengoba umoya oshisayo uvame ukuphakama. Umoya ozungezile uyafudumala futhi wehle ngokuminyana, okuwenza ube nesisindo esincane. Ngakho, igeleza iye phezulu, ivumela umoya ukuba udlule futhi, izivuselele ngokuqhubekayo. Futhi, uma unentshisekelo yokuthi izimvula eziguqukayo zikuthinta kanjani, ungafunda kabanzi ku izimvula ezihamba phambili nokuthi kanjani amagagasi okushisa ayenzeka.

Ngithemba ukuthi lolu lwazi lukusiza ukuthi ufunde kabanzi mayelana ne-convection kanye nokudlulisa ukushisa.
