Kwicandelo lokulinganisa ulwelo, iimitha zokuhamba zesloti ezisemgangathweni zifumene indawo ebalulekileyo ngenxa yoyilo lwazo olwahlukileyo kunye nokusebenza okuthembekileyo. Ezi mitha zenzelwe ukulinganisa ngokuchanekileyo isantya sokuhamba kolwelo olwahlukeneyo, nto leyo eyenza ukuba zibe yimfuneko kumashishini amaninzi.
Iimpawu zoYilo
Uyilo lwemitha yokuhamba kwesloti esemgangathweni ludla ngokubandakanya isithuba esicwangcisiweyo ngokuchanekileyo ngaphakathi kwendlela yokuhamba. Esi sithuba sinokuba seemilo ezahlukeneyo, ezifana nesesixande okanye esilinganayo, kuxhomekeke kwiimfuno ezithile zesicelo. Umzekelo, isithuba sesesixande sidla ngokukhethwa xa uxinano lolwelo luhlala lungaguquki okanye lunokuphambuka okuncinci. Kulula ukulwenza kwaye lunokulinganisa ngokufanelekileyo ukuhamba kwevolumu okanye kobunzima, ngokulula kokuguqulwa phakathi kwezi zimbini. Kwelinye icala, kulwelo olunotshintsho olukhulu loxinano, olufana nolo lubangelwa kukutshintsha kokwakheka kolwelo, ubushushu, okanye ubukho bamaqamza egesi, isithuba sokulinganisa esilinganayo lukhetho olufanelekileyo ngakumbi.
Izixhobo zokwakha zemitha zikhethwa ngononophelo ukuze zimelane nendalo yokubola kolwelo olulinganiswayo. Kwiinkqubo ezibandakanya ulwelo okanye iigesi ezibolayo, kusetyenziswa izinto ezifana neglasi yeborosilicate enodonga olunzima enezikali zeseramikhi ezidityanisiweyo. Olu dibaniso lubonelela ngokumelana nokutshaqeka kunye nokungangeni kweekhemikhali, okuqinisekisa ukuba imitha ihlala ixesha elide kwaye isebenza ngokuchanekileyo.
Imigaqo Yokusebenza
Iimitha zokuhamba zesloti ezisemgangathweni zisebenza ngokusekelwe kwimigaqo-siseko ye-fluid mechanics. Njengoko ulwelo ludlula kwisloti, lufumana utshintsho kwisantya kunye noxinzelelo. Ngokulinganisa olu tshintsho, izinga lokuhamba kolwelo linokufunyanwa. Kwezinye iindlela zoyilo, ukuhla koxinzelelo kwisloti kulinganiswa. Ubudlelwane phakathi kokuhla koxinzelelo kunye nezinga lokuhamba buyalinganiswa, okuvumela ukulinganiswa ngokuchanekileyo kokuhamba. Umzekelo, kwimitha yokuhamba kwesloti esekelwe kuxinzelelo olwahlukileyo, umahluko woxinzelelo phakathi kwamacala aphezulu nasezantsi kwisloti uhambelana nesantya sokuhamba, kwaye ukusuka apho, izinga lokuhamba kwevolumu okanye ubunzima linokubalwa.
Omnye umgaqo osetyenziswayo kukulinganisa ixesha elithathwayo ukuze into elwelo idlule kubude obaziwayo bendawo. Olu vavanyo lwexesha lokudlulisa lunokubonelela ngedatha yesantya sokuhamba kwamanzi echanekileyo kakhulu, ngakumbi kulwelo oluneempawu ezifanayo.
Izicelo
Ezi mitha zokuhamba kwamanzi zisetyenziswa kakhulu kumashishini amaninzi. Kwishishini leekhemikhali, zisetyenziselwa ukulinganisa ukuhamba kweekhemikhali ezahlukeneyo ezibolayo nezingeboliyo ngexesha leenkqubo zemveliso. Amandla emitha yokusingatha iintlobo ezahlukeneyo zolwelo kunye nokulinganisa ngokuchanekileyo amazinga okuhamba kwamanzi kubalulekile ekugcineni umgangatho wemveliso kunye nokuqinisekisa ukusebenza kakuhle kwemveliso.
Kwicandelo lokunyanga amanzi kunye namanzi amdaka, iimitha zokuhamba ezisemgangathweni zidlala indima ebalulekileyo. Zisetyenziselwa ukulinganisa ukuhamba kwamanzi kwizityalo zonyango, ukuqinisekisa ukuba iikhemikhali zisetyenziswa ngokufanelekileyo kwaye iinkqubo zonyango zisebenza kakuhle. Kwiinkqubo zogutyulo lwamanzi amdaka, ezi mitha zinceda ekuboneni ukuhamba kwamanzi amdaka, nto leyo ebalulekileyo ekucwangcisweni kweziseko zophuhliso kunye nokukhuselwa kokusingqongileyo.
Kwishishini leoyile negesi, iimitha zokuhamba ezisemgangathweni zisetyenziselwa ukulinganisa ukuhamba kwee-hydrocarbons kwimibhobho. Nokuba yioyile ekrwada, igesi yendalo, okanye iimveliso ezicociweyo, ukulinganisa ukuhamba ngokuchanekileyo kubalulekile ekudluliseleni ukugcinwa, ukuphucula imveliso, kunye nokhuseleko. Amandla eemitha zokusebenza phantsi kweemeko zoxinzelelo oluphezulu kunye nobushushu obuphezulu azenza zilungele ukusetyenziswa okunjalo okunzima.
Ukuqukumbela, iimitha zokuhamba zesloti ezisemgangathweni, kunye noyilo lwazo olucwangcisiweyo kakuhle, imigaqo yokusebenza ethembekileyo, kunye nokusetyenziswa okuhlukeneyo, ziyinxalenye ebalulekileyo kwicandelo lokulinganisa ulwelo. Uphuhliso lwazo oluqhubekayo kunye nophuculo lumiselwe ukuphucula ngakumbi ukusebenza kwazo kunye nokwandisa uluhlu lwazo lwezicelo kwixesha elizayo.
