摘要
在内燃机实验室建立三维数值模拟,运用流体动力学软件对实验室有无通风两种情况进行模拟,通过比较有送风和无送风两种情况下室内的温度、风速和污染物浓度的分布情况与变化关系,得出此类实验室中合理设计通风系统的必要性,可以有效降低室内温度,除去有害物,以保证室内环境,研究结果为类似试验室的工程设计应用提供参考依据.
Based on the CFD method, 3 D numerical calculation was used to simulate the ventilation system of the internal combustion engine experimental in two different situations. By comparing the diversification and distribution of the indoor air temperature, wind speed and pollutant concentration with and without air supply, we can find out reasonable ventilation design to reduce the indoor temperature, remove pollutant and thus ensure the indoor environment. The result provides a reference for designing and arranging a similar internal combustion engine in engineering applications.
