【正文】 站臺的機械通風(fēng)是通過兩個位于車站末端的噴射的敞口提供空氣給火車和車軌。 Luo and Roux, 2020)。因而 CFD 是現(xiàn)在通俗的設(shè)計工具為了工程師從不同的規(guī)范尋找最優(yōu)的設(shè)計方案 ,由于高成本的復(fù)雜性和條件的限制而通過模擬試驗獲得的方法 (Li and Chow, 2020。這篇 文章驗證和在主要線路上的地鐵通風(fēng)的最優(yōu)化。 Karimipanah and Awbi, 2020). CFD models can be realistically modeled without investing in more costly experimental method (Betta et al., 2020。 Yau et al., 2020。最后這一個地鐵車站站臺的最優(yōu)化通風(fēng)方案被提出來了。 Yau et al., 2020。 大的發(fā)展和高速的電腦和計算的流動性動力學(xué)技術(shù)它有可能運用到 CFD 技術(shù)和預(yù)言空氣的分布狀態(tài)和 優(yōu)化的地鐵通風(fēng)系統(tǒng)設(shè)計的項目。 因此早期的設(shè)計里，有兩個在每邊平臺末端的網(wǎng)格的通風(fēng)口提供給站臺縱向的新鮮空氣和這兩個通風(fēng)口還向火車橫向的噴射空氣。幾何模型展示在圖符 1 中。 Gao et al., 2020。 Somarathne et al., 2020。 Tajadura et al., 2020) have done much work on this. This paper studied the performance of CFD simulation on subway environment control system which has not been studied by other paper or research report. It is essential to calculate and simulate the different designs before the construction begins, since the investment in subway’s construction is huge and the subway should run up for a few decade years. The ventilation of subway is crucial that the passengers should have fresh and high quality air (Lowndes et al., 2020。 外文資料翻譯 第 1 頁 CFD simulation and optimization of the ventilation for subway sideplatform FengDong Yuan *, ShiJun You Abstract To obtain the velocity and temperature field of subway station and the optimized ventilation mode of subway sideplatform station, this paper takes the evaluation and optimization of the ventilation for subway sideplatform station as main line, builds three dimensional models of original and optimization design of the existed and rebuilt station. And using the twoequation turbulence model as its physics model, the thesis makes putational fluid dynamics (CFD) simulation to subway sideplatform station with the boundary conditions collected for simulation putation through field measurement. It is found that the twoequation turbulence model can be used to predict velocity field and temperature field at the station under some reasonable presumptions in the investigation and study. At last, an optimization ventilation mode of subway sideplatform station was put forward. 1. Introduction Computational fluid dynamics (CFD) software is monly used to simulate fluid flows, particularly in plex environments (Chow and Li, 1999。 Gao et al., 2020。 CFD 還可以模擬流動性問題的多種情況 (Gan and Riffat, 2020。 Sigl and Rieker, 2020。盡管天津地鐵現(xiàn)存的各種車站有著不同結(jié)構(gòu)和幾何結(jié)構(gòu) ，西南車站就是最典型的一個。橫向網(wǎng)格通風(fēng)口縱向設(shè)計風(fēng)速為 。基于在地鐵通風(fēng)系統(tǒng)的人工向?qū)б鈭D，這種研究模擬和分析已經(jīng)存在的通風(fēng)系統(tǒng)同時通過專業(yè)軟件 AIRPAK得出天津地鐵原先的車站位置需要重建，然后為重建車站找到最佳的通風(fēng)的項目和結(jié)構(gòu)。 Gehrke et al., 2020). 早期的 CFD 隧道通 風(fēng)系統(tǒng)的模擬大體上集中在緊急情況如著火的情況下 (Modic, 外文資料翻譯 第 9 頁 2020。 1．介紹 CFD（ Computational fluid dynamics） 軟件通常是模擬流動性流程圖。 Gehrke et al., 2020). 外文資料翻譯 第 2 頁 Earlier CFD simulations of tunnel ventilation system mainly focus on emergency situation as fire condition (Modic, 2020。 Papakonstantinou et al., 2020。
