Vhidhiyo iri kuseri kwezviitiko inoratidza chishandiso chakamiswa naMat Staymates, chaanoshandisa kuratidza masikirwo anogona kumisa kupararira kweCOVID-19. Nhau Report-Washington, Mbudzi 10, 2020- Kana iwe ukaona mumwe munhu achidzungaira muchitoro chegirosari kana kumwewo, akapfeka mask ine vharuvhu, uye achida kuziva kuti yakachengetedzeka sei kwauri, saka unofanirwa kutariswa. Matthew Staymates, injiniya wemuchina uye fluid dynamicist paNational Institute of Standards and Technology, ari kudzidza marudzi akasiyana emasiki kuti aone kuti ndeipi inogona kuderedza kutapurirana kwechirwere. Mu "Fluid Physics" neAIP Publishing, akatsanangura kuongorora kwekutanga kuyerera kweN95 masks ane kana asina exhalation valve. Kuti izvi zviitike, akagadzira mavhidhiyo anoshamisa kubva kuSchlieren imaging, nzira yekuona kuyerera kwemvura uye chiedza chinopararira kubva pamusoro pechinhu. Ivhavha yekufemesa paN95 mask yakagadzirirwa kuvandudza kunyaradza kwemushandisi nekudzikisira kupikisa kwesefa panguva yekufema. Staymates akati: "Kana iwe uchifemesa, chidimbu chidiki chinovhurwa, kuitira kuti mweya unoburitswa usingasefa kuburikidza nemasiki zvinhu." "Ndinogona kuratidza nemaziso maitiro ekushanda kwevhavha yekufema, uye kuienzanisa nevhavha yakadaro. N95 yakaenzaniswa." VaStaymates vakati tsvagiridzo yake inoratidza kuti maN95 masiki ane mavharuvhu ekufema haana kukodzera kusefa madonhwe ekufema kubva kuvanhu. Iye akati: "Nzwisiso yedu iripo ndeyekuti chikamu cheCCIDID-19 chinoparadzirwa nemadonhwe ekufema, saka panguva yedenda iri, N95 ine vharuvhu haikodzeri kudzora." Akaona kuti iyo N95 mask isina vharafu inogona kudzivirira zvakanyanya madonhwe emvura kuti asapinda mumasiki zvinhu. Staymates akagadzira yakanakisa-yemamiriro ekunze murabhoritari mumusangano wake wehuni yekuyedza mhando dzakasiyana dzemasiki uye zvinhu. Akagadzira dhizaini yekufemesa kuti atevedzere mafambiro ekufema kwevanhu chaivo, uye akagadzira yakagadziridzwa pneumatic velocimeter kuti ayere yake yekufema kuyerera kwecurve. Akashandisa iyi data seyero yeartificial exhalation system. Staymates akati: "Ini zvakare ndakagadzira uye ndakavaka generator fog generator mukati memusoro wemannequin. Iyo fog generator inopa madonhwe akafanana zvakanyanya neaya akaparadzirwa nevanhu." Exhale, uye jenareta remhute rinotoita kuti riite sekunge riri kuputa fodya." Akataura kuti kushandiswa kwe schlieren imaging uye mamwe matekinoroji ekuona kuyerera "kuchaenderera mberi kutibatsira kunzwisisa zviri nani kuti masiki nemask kumeso anoita basa mukupararira. chechirwere ichi." "Ndinovimba kuti basa iri richabatsira kuti vateereri vazive Mukuita kwedu kwakabatana padenda repasi rose, mavharuvhu ane masiki haabatsire." Matthew Staymates akanyora "Kuyerera kwekuona uchishandisa schlieren imaging uye kupararira kwechiedza pa. N95 respirators ane uye asina exhalation valve".
