Inkcazelo emfutshane yeendaba ezinemingxuma
Njengomphandi onamava kwicandelo le-fluid dynamics kunye neziganeko zothutho, ndingakuxelela loo ntoimidiya eneemboboNangona zikho kuyo yonke indawo kubomi bethu bemihla ngemihla, zihlala zinganakwa ngendima ebalulekileyo eziyidlalayo kwiinkqubo ezahlukeneyo zoshishino, okusingqongileyo, kunye nebhayoloji. Ukususela emhlabeni ongaphantsi kweenyawo zethu ukuya kwiinkqubo zokucoca kwizixhobo zethu kwanakwisakhiwo sangaphakathi samathambo ethu,imidiya eneembobozikho kuyo yonke indawo, zixhasa ngokuthe cwaka iindlela ezigcina ihlabathi lethu lisebenza.
Imithombo yeendaba eneembobo ibhekisa kwizinto ezigcwele iimbobo okanye imingxunya. Ezi mbobo, okanye 'ii-interstices,' zihlala zidibene, zenza i-labyrinth yemijelo apho ulwelo lunokuhamba khona. Imizekelo yemithombo yeendaba yendalo eneembobo ibandakanya umhlaba, amatye e-sedimentary, kunye nomthi, ngelixa imithombo yeendaba eneembobo zokwenziwa iquka izinto ezifana ne-ceramics, i-metallic foams, kunye neentlobo ezithile zeefilitha ezisekelwe kwi-polymer.
Inkalo enomdla yemidiya eneembobo yingcamango 'yeembobo' - igama elilinganisa ubungakanani bendawo engenanto kwisixhobo. Iimbobo zimisela ukuba zingakanani ulwelo olunokugcinwa yile nto kwaye zinokuthutha njani la manzi, nokuba ngamanzi, ioyile, okanye nomoya. Ezi mpawu zenza imidiya eneembobo ibe ngumdlali obalulekileyo kwiindawo ezahlukeneyo ezifana ne-hydrology yamanzi angaphantsi komhlaba, ukubuyiswa kweoyile, ukulungiswa kongcoliseko, kunye nokufakelwa kwezonyango.
Njengoko singena nzulu kwisifundo semidiya eneembobo, siza kuhlaziya iingcamango ezintsonkothileyo ezifana nokuvuleka kwamanzi, ulwakhiwo lwembobo, ukuhamba kolwelo, kunye nomthetho kaDarcy, imigaqo eyakhelwe phezu kokuqonda okusisiseko kwembobo. Siza kuhlola nendlela imidiya eneembobo ezihlulwe ngayo, iimpawu zayo zomzimba, kunye nezicelo ezininzi zehlabathi lokwenyani abazifumeneyo kumashishini ahlukeneyo.
Ukufunda ngeendaba ezinamagqabi akuyonto nje yesayensi. Luhambo olutyhila uthungelwano olungabonakaliyo ngaphakathi kwezinto, isenzo esincinci se-capillary esiqhuba uthutho oluhambayo, kunye nendima enamandla edlalwa zezi zinto kumacandelo ahlukeneyo. Njengomntu ozinikele inxalenye ebalulekileyo yomsebenzi wam ekuphononongeni ezi zinto zintsonkothileyo, ndiyakumema ukuba ujoyine nam njengoko sijonga kwihlabathi elinomtsalane leendaba ezinamagqabi.
Imigaqo esisiseko yeendaba ezivulekayo
Imigaqo esisiseko yeendaba ezinamagqabi ayicacanga kodwa iyathandeka. Le migaqo ichaphazela izinto zendalo kunye neenkqubo ezenziwe ngabantu ngokufanayo, ngoko ke ukuyiqonda kuvula indlela yokuqonda okutsha kunye nokuqhubela phambili. Masifumanise imigaqo esisiseko yeendaba ezinamagqabi kwaye sijonge indlela ezilawula ngayo ihlabathi lethu.
Umgaqo wokuqala ophambili ujikeleza ingcamango ye-porosity. Oku kulinganisa indawo engenanto okanye i-pore kwisixhobo xa kuthelekiswa nomthamo waso uwonke. Ungacinga ngesiponji, esinemingxuma evumela amanzi ukuba angene aze agcinwe. I-porosity yesixhobo ichaphazela kakhulu amandla ayo okugcina nokuthutha ulwelo, into esetyenziswa kumashishini afana nokubuyiswa kweoyile kunye nobunjineli bendalo.
Okulandelayo kukungena kwamanzi, okulinganisa amandla esixhobo esineembobo zokuvumela ulwelo ukuba ludlule kuso. Khawuthelekelele ugalela amanzi kwijagi egcwele isanti. Isantya amanzi angena ngaso entlabathini siyindlela yokulinganisa ukungena kwamanzi entlabathini. Lo mgaqo awupheleli nje kuphela kwisanti okanye emhlabeni, kodwa ubalulekile kwiindawo ezifana ne-hydrology yamanzi angaphantsi komhlaba kwanakwicandelo lezonyango, apho ukungena kwamanzi emathanjeni kuchaphazela iinkqubo zokuhambisa amayeza.
Ukuqondaisakhiwo semboboKwakhona kubalulekile xa kufundwa ngeendawo ezinemingxuma. Oku kuquka ukuphonononga ubungakanani, imilo, kunye nokusasazwa kweemingxuma ngaphakathi kwendawo enemingxuma. Ulwakhiwo lwemingxuma ludla ngokumisela amandla oomatshini esixhobo, iimpawu zobushushu, kunye nokusebenza kwamakhemikhali, nto leyo echaphazela ukufaneleka kwaso kwiindlela ezahlukeneyo zokusebenza, ukusuka kwiinkqubo zokucoca ukuya kwizixhobo zokutshintsha ubushushu.
Okokugqibela, umgaqo obalulekileyo onxulumene nokuhamba kolwelo kwimidiya eneembobo ngumthetho kaDarcy. Lo mthetho, owaqulunqwa yinjineli yaseFransi uHenry Darcy kwinkulungwane ye-19, unika inkcazo yezibalo yokuhamba kolwelo kwisixhobo esineembobo. Umthetho kaDarcy usetyenziswa kakhulu kwimodeli yamanzi angaphantsi komhlaba, ubunjineli bamachibi, kunye noyilo lweenkqubo ezahlukeneyo zokucoca.
Le migaqo isisiseko yemidiya eneembobo ibeka isiseko sophando olunzulu nolupheleleyo ngalo mbandela. Njengomntu ochithe iminyaka egxile kwisayensi yemidiya eneembobo, ndinomdla wokwabelana nawe ngezinto ezintsonkothileyo kunye nobunzima beli candelo. Njengoko siqhubeka nohambo, siza kujonga indlela yokwahlulahlula imidiya eneembobo, iimpawu zayo zomzimba, kunye nezicelo ezininzi zehlabathi lokwenyani ezizinikezelayo. Zibophelele olu hambo lwesayensi!

Ukuqonda ukuxinana kwamanzi kunye nokungangeni kwamanzi komhlaba kunokunceda ukuqikelela ukutsalwa kwamanzi, ukuthuthwa kwezondlo, kunye nokungena kweengcambu, kunika ulwazi ngezenzo zolimo kunye nolawulo lokusingqongileyo.
8. Ngaba imithombo eneembobo ingahambisa ubushushu?
Ewe, imidiya eneembobo inokuhambisa ubushushu, nangona idla ngokuba buthathaka kunezixhobo ezingenazo iimbobo. Inkqubo yokuhambisa ubushushu kwimidiya eneembobo iyinkimbinkimbi, ibandakanya ukuhambisa nge-matrix eqinileyo kunye nolwelo olukwiimbobo, kunye nokudluliselwa kobushushu obujikelezayo ukuba ulwelo luhamba.
9. Izinto ezinemingxuma zinxulumene njani ne-acoustics?
Izinto ezinemingxuma zidlala indima ebalulekileyo ekufunxeni isandi kunye nokulawula ingxolo. Ulwakhiwo oluntsonkothileyo lweemingxuma lunokubamba amaza esandi, luguqule amandla azo abe bubushushu kwaye lunciphise ubungakanani besandi esibuyiswayo. Oku kwenza izinto ezinemingxuma zibe zilungele ukusetyenziswa njenge-acoustic insulation kunye neepaneli zokunciphisa ingxolo.
10. Iimpawu zemidiya eneembobo zenziwe njani?
Ukumodela iipropati zemidiya eneembobo kubandakanya iindlela ezintsonkothileyo zezibalo kunye neendlela zokubala. Ezi modeli zinokuqala kwiimodeli zesikali sembobo, zibambe ulwakhiwo oluneenkcukacha lwenethiwekhi yembobo, ukuya kwiimodeli eziqhubekayo ezichaza indlela yokuziphatha engumndilili kwivolumu enkulu.
11. Ziziphi ezinye zeengxaki zokusebenza ngemidiya eneentunja?
Imingeni ngemidiya eneembobo idla ngokunxulumene nokuchonga nokuqikelela indlela eziziphatha ngayo phantsi kweemeko ezahlukeneyo. Umzekelo, ukumisela ngokuchanekileyo ukusasazwa kobukhulu beembobo okanye ukuqonda indlela utshintsho lwesakhiwo kwimidiya oluchaphazela ngayo ukuhamba kolwelo kunokuba nzima. Kwakhona, xa kusetyenzwa ngemidiya yendalo enembobo efana namatye okanye umhlaba, ukungafani kwazo okungokwemvelo kongeza umaleko owongezelelweyo wobunzima.
12. Ziziphi ezinye zeendlela zexesha elizayo kuphando lweendaba olunemingxuma?
Imiyalelo yexesha elizayo kuphando lweendaba ezinemibhobho mikhulu kwaye ibandakanya izifundo ezahlukeneyo. Zibandakanya ukuphuhlisa izixhobo ezintsha ezinemibhobho eyenzelwe ukusetyenziswa okuthile, ukuphucula ukuqonda kwethu izinto zothutho kwiinkqubo ezinemibhobho, kunye nokuphucula amandla ethu okumisela imodeli. Iindawo zophando ezifana nezixhobo ezinemibhobho emincinci kunye nezakhiwo ezinemibhobho eziphefumlelwe yi-bio nazo ziya zikhula, zivula imida emitsha yokufumanisa kunye nokuvelisa izinto ezintsha.
Kwihlabathi elihlala litshintsha leendaba ezivulekayo, le yeminye yemibuzo ebuzwa rhoqo. Nangona kunjalo, ukufuna ulwazi akupheli apha. Njengoko izazinzulu kunye neenjineli ziqhubeka nokuhlola eli candelo linomdla, ikamva lithembisa ubutyebi bezinto ezintsha ezifunyenweyo, ubuchwepheshe kunye nokusetyenziswa okunokuhlolwa.
Unomdla wokufunda ngakumbi ngeendaba ezivulekayo?
