VIGA Faucet Mugadziri 
Nguva pfupi yadarika masayendisiti akagadzirisa chirahwe chiri kuseri kweimwe yeanonyanya kuzivikanwa uye anogumbura manzwi emumba.: ruzha rwemvura inodonha. Crucially, vakawanawo mhinduro iri nyore kuimisa, uye vazhinji vedu takawana mhinduro mumakicheni edu. Kudonhedza faucet masayendisiti akagadzirisa pikicha kuseri kweimwe yeanonyanya kuzivikanwa uye anogumbura manzwi emumba.: ruzha rwemvura inodonha. Crucially, vakawanawo mhinduro iri nyore kuimisa, uye vazhinji vedu takawana mhinduro mumakicheni edu. Kushandisa ultrafast makamera uye zvemazuva ano odhiyo kutora matekiniki, vaongorori vepaYunivhesiti yeCambridge vakawana kuti “plink, plink” inzwi rinobudiswa kana donhwe remvura richirova pamusoro pemvura harikonzerwi nedonhwe racho pacharo, asi nekuzunguzika kwematuru madiki akavharirwa pasi pemvura. Mafuro anomanikidza pamusoro pemvura kuti azvizungunuke, kufambisa ruzha rwemhepo kunge piston. Pamusoro pe, vatsvakurudzi vakawana kuti kuchinja kwepamusoro tension, sekuwedzera sipo yendiro, aigona kuvhara ruzha. Zvakawanikwa zvakaburitswa mupepanhau Scientific Reports. Kunyangwe vanhu vakamutswa kwezvizvarwa kune ruzha rwemvura inodonha kubva papombi inodonha kana padenga., kwakabva inzwi harina kumbozivikanwa. Dr Anurag Agarwal weYunivhesiti yeCambridge Dhipatimendi reUinjiniya, uyo akatungamirira chidzidzo, akadaro: “Zvakawanda zvakaitwa pafizikisi yekudonha matepi, asi hapana zvizhinji zvakaitwa pakunzwika. “Asi nekuda kwevhidhiyo yemazuva ano uye tekinoroji yekuteerera, tinopedzisira takwanisa kuona panobva inzwi racho, izvo zvingatibatsira kuzvimisa. "Agarwal ndiye mukuru weacoustics lab uye muongorori kuEmmanuel College, uyo akatanga kusarudza kunzvera chinetso chacho paakashanyira shamwari yakanga ine mvura zhinji padenga rake. Chidzidzo chaAgarwal chakaongorora acoustics uye aerodynamics yeaerospace, midziyo yemumba uye biomedical application. Akadaro: Pandakazopepuka ndanzwa ruzha rwemvura yaidonha, Ndakatanga kufunga nezvazvo. “Zuva rakatevera, Nyaya iyi ndakaikurukura neshamwari yangu neimwewo shasha yekushanya, uye tese takashamisika kuti hapana akanyatsopindura chikonzero chezwi. "Agarwal akabatana naDr. Peter Jordan anobva kuYunivhesiti yePoitiers (uyo akapedza nguva muCambridge kuburikidza neEmmanuel College kuyanana) uye mukuru Sam Phillips pakuedza kudzidza dambudziko. Chishandiso chavo chinoshandisa kamera inokurumidza, maikorofoni uye hydrophone kurekodha madonhwe emvura anowira mutangi. Madonhwe emvura ave ari manyuko ekuda kuziva kunharaunda yesainzi kweanopfuura zana ramakore: mafoto ekutanga emadonhwe emvura achirova akaburitswa mukati 1908, uye kubvira ipapo masayendisiti ave achinetseka kuwana kwaibva inzwi racho. Iyo hydrodynamics yemadonhwe emvura anorova pamusoro pemvura inozivikanwa kwazvo: kana donhwe remvura richirova pamusoro, inokonzera kuumbwa kwegomba, iyo inodzokera shure nekukasira nekuda kwekumanikidzana kwepamusoro kwemvura, zvichiita kuti murwi wemvura usimuke. Iyo mhango yakadzoka nekukasira mushure mekunge donhwe rarova, zvichiita kuti tuturu twemhepo tunyure pasi pemvura. Zvidzidzo zvakapfuura zvakafungidzira kuti “Prink” inzwi rinokonzerwa nekukanganisa kwacho, mhango resonance kana pasi pemvura inonzwika munda inopararira nemumvura, asi izvi hazvigone kusimbiswa nekuedza. Vatsvagiri vepaYunivhesiti yeCambridge vakawana mukuedza kwavo izvo, zvimwe zvinopesana-intuitively, kuputika kwekutanga, kuumbwa kwegomba uye kubuda kwemvura zvese zvakanyarara. Kunobva ruzha mabhuru akabatwa. Phillips, zvino mudzidzi wePhD mudhipatimendi reinjiniya, akadaro: “Kushandisa high-speed makamera uye high-sensitivity maikorofoni, isu takakwanisa kuona zvakananga oscillations yemabhuru kekutanga, kuratidza kuti mabubbles ndiye mutyairi mukuru weinzwi repasi pemvura uye yakasarudzika 'plink’ ruzha pabhodhi. “Zvisinei, ruzha rwuri mumhepo hachingori pasi pemvura inonzwika ndima inopararira kumusoro, sezvaimbofungwa, Kuitira kuti “base” kuva yakakosha, iyo yakavharirwa mabhubhu emhepo inoda kuve pedyo nepasi pegomba rinokonzerwa nekukanganisa kwekudonha. Mabubbles anobva afambisa kutenderera kwemvura pazasi pegomba, kunge piston inotumira masaisai eruzha mudenga. Iyi ndiyo nzira inoshanda zvikuru iyo mabhavhu epasi pemvura anotyaira nzvimbo yekurira inofambiswa nemhepo kupfuura yaimbotaurwa. Maererano nevatsvakurudzi, nepo chidzidzo chacho chaiitwa nokuda kwokuda kuziva, mhedzisiro yacho inogona kushandiswa kugadzira nzira dzinoshanda dzekuyera kunaya kwemvura, kana kugadzira manzwi anogutsa ezvinodonhedza mvura mumitambo kana mafirimu, izvo zvisati zvaitika.
