摘要:
为研究舱室内害气体泄露过程,减少有害气体对乘载员的危害。采用Navier-Stokes方程与RNG k-ε湍流模型,利用计算流体力学(CFD)理论方法,建立有害气体泄漏的数值计算模型。以某型车辆为例,对车舱内有害气体泄漏扩散过程进行数值模拟,计算得到舱室内有害气体各组分在舱内空间分布及舱室内有害气体泄漏扩散的一般规律。分析结果表明,文中计算方法有效地捕捉到舱内有害气体运动过程以及浓度变化过程,可为舱室有害气体控制设计与评价提供理论基础。
Abstract:
Abstract:In order to study the process of harmful gas leakage in the cabin and reduce harmful gases to passengers,the numerical simulation method is established using the CFD method based on Navier-Stokes equation and RNG k-ε turbulence model.And the harmful gas released from a fixed point source in a cabin are simulated as an example,the distribution of harmful gas components and the information of the gas leak and diffusion laws in the cabin are obtained.The results showed that,this method can capture harmful gas motion and concentration change with time in cabin,and provide theoretical basis for control method design and evaluation of the harmful gas in cabin.
