摘 要:采用Gambit軟件建立B型地鐵列車三維模型,并用Gambit軟件進(jìn)行網(wǎng)格劃分,建立邊界條件;利用計(jì)算流體動(dòng)力學(xué)(CFD)軟件Fluent,應(yīng)用k-ε兩方程湍流模型對氣流組織進(jìn)行了數(shù)值計(jì)算。討論了在相同送風(fēng)量的條件下,不同送風(fēng)風(fēng)速對車廂內(nèi)溫度場和速度場的影響。

關(guān)鍵詞:地鐵車輛;氣流組織,數(shù)字模擬

Numerical simulation of air distribution in air conditioning system of Type B metro vehicles

Abstract: This paper uses gambit software to build a three-dimensional model of Type B subway train, and uses gambit software to mesh and establish boundary conditions. Using CFD software Fluent, the turbulence model of k-ε equation was used to calculate the airflow distribution. The paper discusses the influence of different air supply speeds on the temperature field and velocity field in the train compartment under the same air supply volume.

Key words: metro vehicle;airflow organization;numerical simulation

當(dāng)今社會(huì)經(jīng)濟(jì)的高速發(fā)展和人民生活質(zhì)量的日益提高,地鐵列車作為新型的交通工具,它的迅速發(fā)展,從某種角度來講,代表一個(gè)城市的發(fā)達(dá)程度,因此地鐵的發(fā)展必將受到高度重視。(剩余3842字)
