【摘要】：本文構(gòu)建了含呼吸道周邊黏液層和組織的口喉呼吸道模型,實(shí)現(xiàn)了黏液層上水蒸氣組分輸運(yùn)和對(duì)流傳熱、黏液層內(nèi)汽化潛熱和黏液層及呼吸道周邊組織內(nèi)的導(dǎo)熱模擬,在27.6°C,相對(duì)濕度34.7%空氣入口條件下分別模擬了在1)考慮呼吸道、黏液層及組織導(dǎo)熱、對(duì)流和汽化潛熱和2)呼吸道壁面恒定37°C兩種邊界條件下的理想口喉模型中多組分吸濕性顆粒物的運(yùn)動(dòng)和沉積。結(jié)果表明,條件1平均相對(duì)濕度較條件2高2.3%,但顆粒物沉積率比條件2小,最大差異可達(dá)9%;顆粒物沉積形式類(lèi)似,但條件1下沉積的顆粒物平均直徑比條件2小40.7%,逃逸顆粒物平均直徑小14.3%。
[Abstract]:In this paper, an oral and laryngeal respiratory tract model containing the mucus layer and tissue around the respiratory tract is constructed. The transport and convection heat transfer of water vapor components on the mucus layer, the latent heat of vaporization in the mucus layer and the heat conduction in the mucus layer and the surrounding tissues of the respiratory tract are simulated. At 27.6 擄C and relative humidity of 34.7% air inlet, respectively, at 1) respiratory tract, mucus layer and tissue heat conduction were taken into account. Movement and deposition of multi-component hygroscopic particles in an ideal mouth-throat model with convection and vaporization latent heat and 2) respiratory tract wall constant at 37 擄C boundary conditions. The average relative humidity of condition 1 was 2.3 higher than that of condition 2, but the deposition rate of particulate matter was smaller than that of condition 2, and the biggest difference could be as high as 9, but the average diameter of particles deposited under condition 1 was 40.7 smaller than that of condition 2, and the average diameter of escaping particles was 14.3cm.
