Umsindo wokudonsa amanzi kusuka esikulungeni

Muva nje ososayensi baxazulule iphazili ngemuva komunye wemisindo yasendlini eyaziwa kakhulu necasulayo.: umsindo wamanzi aconsayo. Ngokubalulekile, bathola nekhambi elilula lokuyimisa, futhi iningi lethu lisitholile leso sixazululo emakhishini ethu. Ososayensi bompompi oconsayo baxazulule iphazili ngemuva komunye wemisindo yasendlini eyaziwa kakhulu necasulayo.: umsindo wamanzi aconsayo. Ngokubalulekile, bathola nekhambi elilula lokuyimisa, futhi iningi lethu lisitholile leso sixazululo emakhishini ethu. Ukusebenzisa amakhamera ashesha kakhulu nezindlela zesimanje zokuthwebula umsindo, abacwaningi eNyuvesi yaseCambridge bathole ukuthi “xhuma, xhuma” umsindo okhiqizwa lapho iconsi lamanzi lishaya phezu koketshezi alubangelwa ithonsi ngokwalo, kodwa ngokudlidliza kwamabhamuza amancane avaleleke ngaphansi kwamanzi. Amabhamuza aphoqa amanzi ukuthi azidlidlize ngokwawo, ukushayela umsindo ophuma emoyeni njengepiston. Ngaphezu kwalokho, abacwaningi bathola ukuthi ukushintsha ukungezwani kwendawo, njengokwengeza insipho yezitsha, ingavimba umsindo. Okutholakele kushicilelwe kumagazini Imibiko Yesayensi. Yize abantu sebevuswa izizukulwane ngezizukulwane bezwa umsindo wokuconsa kwamanzi kumpompi ovuzayo noma ophahleni., umthombo oqondile womsindo awukaze waziwe. UDkt Anurag Agarwal woMnyango Wezobunjiniyela waseNyuvesi yaseCambridge, obehola ucwaningo, wathi: “Kuningi osekwenziwe ku-physics yompompi abaconsayo, kodwa akukuningi okwenziwe ngomsindo. “Kodwa ngenxa yobuchwepheshe besimanje bevidiyo nomsindo, ekugcineni siyakwazi ukukhomba umthombo womsindo, okungase kusisize sikumise. "U-Agarwal uyinhloko yelebhu ye-acoustics futhi ungumcwaningi e-Emmanuel College, owanquma okokuqala ukuphenya le nkinga lapho evakashele umngane owavuza indawo encane ophahleni lwakhe. Ucwaningo luka-Agarwal lwaphenya i-acoustics kanye ne-aerodynamics ye-aerospace, izinto zasendlini kanye nezicelo ze-biomedical. Uthe: Lapho ngiphaphama ngizwa umsindo wokuwa kwamanzi, Ngaqala ukucabanga ngakho. “Ngosuku olulandelayo, Ngaxoxa ngalolu daba nomngane wami kanye nesinye isifundiswa esivakashile, futhi sobabili samangala ukuthi akekho ngempela owaphendula isizathu sezwi. “U-Agarwal usebenzisane noDkt. Peter Jordan waseNyuvesi yasePoitiers (ochithe isikhathi eCambridge ngobudlelwano be-Emmanuel College) kanye no-Sam Phillips omkhulu ocwaningweni lokutadisha le nkinga. Idivayisi yabo isebenzisa ikhamera eshesha kakhulu, imakrofoni kanye ne-hydrophone ukurekhoda amaconsi amanzi awela ethangini. Amaconsi amanzi abelokhu ewumthombo welukuluku emphakathini wesayensi iminyaka engaphezu kwekhulu: izithombe zakuqala zamaconsi amanzi ashayayo zashicilelwa 1908, futhi kusukela lapho ososayensi baye bazama ukuthola umthombo womsindo. I-hydrodynamics yamaconsi amanzi ashaya uketshezi olungaphezulu kwaziwa kahle: lapho iconsi lamanzi lishaya phezulu, kubangela ukwakheka komgodi, ehlehla ngokushesha ngenxa yokushuba koketshezi, okwenza ikholomu ye-liquid ikhuphuke. I-cavity yabuya ngokushesha kakhulu ngemva kokushaya kwe-droplet, okwenza amabhamuza amancane avaleleke ngaphansi kwamanzi. Ucwaningo lwangaphambilini luveze ukuthi “Phuma” umsindo ubangelwa umthelela ngokwawo, i-cavity resonance noma insimu yomsindo engaphansi kwamanzi esakazeka emanzini, kodwa lokhu akunakuqinisekiswa ngokuhlola. Abacwaningi eNyuvesi yaseCambridge bathola ekuhloleni kwabo lokho, ngandlela-thile counter-intuitively, ukuqhuma kokuqala, ukwakheka komgodi kanye nokukhipha uketshezi konke kwathuliswa ngempumelelo. Umthombo womsindo amabhamuza anqanyuliwe. Phillips, manje usengumfundi we-PhD emnyangweni wobunjiniyela, wathi: “Ukusebenzisa amakhamera anesivinini esikhulu kanye namakrofoni azwela kakhulu, sakwazi ukubona ngokuqondile ukuzungeza kwamabhamuza okokuqala ngqa, okubonisa ukuthi amabhamuza angumshayeli oyinhloko womsindo ongaphansi kwamanzi kanye ‘ne-plink’ umsindo ebhodini. “Nokho, umsindo osemoyeni awuwona nje umkhakha womsindo ongaphansi kwamanzi osakazekela phezulu, njengoba bekucatshangwa ngaphambilini, Ukuze i- “isisekelo” ukuze kube okubalulekile, amabhamuza omoya abanjiwe adinga ukuba seduze nendawo engaphansi kwembobo ebangelwa umthelela wokuwa. Amabhamuza abe eseshayela i-oscillation yendawo yamanzi ngaphansi komgodi, njengepiston ethumela amaza omsindo emoyeni. Lena indlela esebenza ngempumelelo kakhulu lapho amabhamuza angaphansi kwamanzi eshayela khona inkambu yomsindo osemoyeni kunalokho okwakuphakanyiswe ngaphambilini. Ngokusho kwabacwaningi, ngenkathi ucwaningo lwenziwa ngenxa yelukuluku lokufuna ukwazi, imiphumela ingase isetshenziselwe ukuthuthukisa izindlela ezisebenza kahle kakhulu zokukala imvula, noma ukuthuthukisa imisindo yokwenziwa ekholisayo yamaconsi amanzi emidlalweni noma kumamuvi, okungakafezeki.
