Ukuza kuthi ga ngoku, sele ulubonile "uphononongo" lwaseBelgian-Dutch malunga nendlela ukulinganisa okubonakalayo kwe-aerodynamics ebonisa ukuba kufuneka sibaleke kwaye sikhwele ibhayisekile siqelelene ngakumbi ngeli xesha lobhubhani we-coronavirus.
El nqaku Uphononongo lwaseBelgium-Dutch: Kutheni ngamaxesha e-COVID-19 ungakwazi ukuhamba / ukubaleka / ukukhwela ibhayisekile kufutshane nomnye umntu?, ayithembekanga ngokupheleleyo. Ifakwe kwiqonga lasimahla (eliPhakathi) elivumela nabani na ukuba apapashe kwaye ayifuni kujongwa nyani. Ngelishwa, oku kufana nomlilo wasendle kumajelo eendaba ezentlalo, abantu begxile kuzo zombini isihloko kunye nesiphelo senqaku:
“Gcina umgama omalunga neemitha ezine ukuya kwezintlanu emva komntu okhokelayo ngelixa uhamba, iimitha ezilishumi xa ubaleka okanye ukhwele ibhayisekile kancinci, kwaye ubuncinci iimitha ezingamashumi amabini xa uhamba ngebhayisekile ngokukhawuleza. "Ukuba ufuna ukudlula umntu, kukwacetyiswa ukuba uqale 'isilumkiso' kwilungiselelo elishiyanayo ukusuka kumgama omde kakhulu - iimitha ezingamashumi amabini ngeebhayisekile, umzekelo, ukuze ukwazi ukudlula ngononophelo kwaye kumgama ofanelekileyo. ihamba ngomgca othe tye."
Kulula kakhulu ukuphambana xa ngoku ufunda ukuba kufuneka uhlale ngaphezu kweemitha ezilishumi kude nembaleki kunye neemitha ezingama-20 ukusuka kumkhweli webhayisikile ophambi kwakho. Kwezinye iindawo, oku akunakwenzeka. Kodwa thatha umoya onzulu, kwaye uhlale kude noluntu. Olu xwebhu ayilophononongo lophando okanye isifundo malunga nokusasazeka kwezifo."
Ukucaca, i-coronavirus imbi kakhulu, kwaye sivuma ngokuqinileyo ukuba wonke umntu kufuneka abaleke kwaye ahambe yedwa, eshiya umgama ocetyiswayo okhoyo oziimitha ezili-10 phakathi kwakho nabanye nangaphezulu apho kunokwenzeka. Kodwa nantsi isizathu sokuba ungalithengi ngokupheleleyo eli nqaku litsha.
Olu lulinganiso lwentsholongwane olungajongwanga ntanga.
Oku kubaluleke kakhulu "iphepha elimhlophe", iphepha lesikhundla elibhaliweyo ngumntu onegunya ngesihloko, kulo mzekelo iqela labaphandi bezemidlalo be-aerodynamic kunye neenjineli ezivela eBelgium naseNetherlands, kodwa kungekhona iphepha elihlaziywa ngontanga.
Isizathu sokuba ukuphononongwa koontanga kubaluleke kakhulu kukuba kunyanzeliswa imigangatho ephezulu yendlela yesayensi kwaye iqinisekisa ukuba amabango angenabungqina, izigqibo zobuxoki, ukutolika okungamkelekanga, okanye iimbono zomntu azipapashwa ngaphandle kokuphononongwa koontanga. Yicinge njengeengcali ezijonga kabini umsebenzi wezinye iingcali.
Sekunjalo, ukusebenzisa iimodeli kunye namanani aphilileyo asetyenziswa ukuqonda izibonelelo zokuzoba (ukukhwela ibhayisekile okanye ukubaleka) ukuphucula ukusebenza kweimbaleki ezikumgangatho ophezulu, abaphandi basebenzise imodeli ye-computational fluid dynamics (CFD) ukulinganisa ukukhutshwa kwamasuntswana amathe kubantu abahamba okanye ababalekayo kuqwalaselo olwahlukileyo ukubona ukuba mangaphi amathontsi amakhulu namancinane anokushiywa ngasemva.
Bagqibe kwelokuba ukusondela kakhulu emntwini, nokuba kumgama ocetyiswayo ngoku we-10 yeemitha, kuyingozi ngenxa "yelifu lamathontsi" abawashiya ngasemva.
Ingxaki yile akukho nanye kwezi eqinisekisiweyo, kuquka ukulinganisa CFD ngokwayo. Ngamagama abaphandi:Ukulinganisa kwe-CFD kwenziwa nge-Ansys Fluent CFD, kwakhiwa kwizifundo ezingqingqwa zangaphambili zokukhutshwa kweegesi kunye namasuntswana kwizantya ezahlukeneyo malunga neemannequins ezipheleleyo ezimele imizimba yabantu. Ezi zifundo zokuqinisekisa ziya kuxelwa kupapasho lwenzululwazi oluphononongwe ngoontanga ukuba luvele kamva.«.
Ngamanye amagama, Abaphandi bathi banalo luvo bakholelwa ukuba ichanekile, kodwa abakayiqinisekisi okanye bayihlaziye. Umphandi ophambili uBert Blocken uthe kwimpendulo ye-Twitter bakhawuleze ukwabelana ngeziphumo kuba le ngxaki yimeko engxamisekileyo kwihlabathi liphela apho abantu besifa kwaye uqoqosho lusihla.
Nangona injongo yayintle, ezinye iingcali, kuquka iinjineli zeCFD, ziye zalibazisa ukusebenzisa le mifuziselo ngeenjongo zempilo yoluntu, ngenxa yokuba le mizekelo ayizozixhobo ezifanelekileyo zolu hlobo lophando.
Ukulinganisa kwikhompyuter kunokulunga ekuboniseni ukuba kungakanani ukuxhathisa komoya onokujamelana nako kugqatso okanye imeko yogqatso lweqela, kodwa kunokuba nesiphako ngokwemigaqo yebhayoloji. Azikho iikhompyutha ezikwaziyo ukuxelisa izinto eziguquguqukayo ezingenakubalwa ezenzeka kwibhayoloji.
Ukulunga, uBlocken uye wakwenza kwacaca ukuba eyakhe umsebenzi aerodynamic kwaye hayi virological. Kwenye impendulo ye-Twitter, uthe: "Amathontsi ajika abe ngumphunga ngokukhawuleza. Umbuzo ngowokuba kwenzeka ntoni kwintsholongwane kumbindi oqinileyo: ingaba isasebenza ekosuleleni? Abanye bayaphikisana ewe, ndiyathandabuza. Amazinga osulelo anokuba phezulu kakhulu«.
Oko kukuthi, xa amachaphaza ephuphuma emoyeni, Ngaba intsholongwane inokukosulela ngelixa uhleli njengesuntswana elomileyo emoyeni? Uhlalutyo lwamatyala angaphezulu kwe-75,000 e-COVID-19 e-China alufumananga uhlobo olunjalo losulelo ngomoya.
Sikuqonda. La maxesha othusayo, anoxinzelelo, kwaye angaqinisekanga xa iindaba zitshintsha ngemini, ukuba akunjalo ngeyure. Akukho mntu ufuna ukuba nekratshi, kwaye sonke sifuna iimpendulo. Kodwa kubalulekile ukuba ungakhawulezi uthabathe ubungqina obungaphelelanga kwaye ugcwalise izikhewu ngokusekelwe kuqikelelo.
Ekugqibeleni, iingcebiso zisamile: hlala ekhaya kangangoko unako. Hlamba izandla rhoqo. Nxiba i-bandana ukuba uya kuba kwiindawo ezinezithuthi eziphezulu. Ukuba uziva ugula, hlala ekhaya.
