【摘要】 结合某发动机试验室的具体情况 ,对受限CO射流扩散规律进行了三维数值模拟 ,分析了通风量和送风温度对于CO扩散的影响 ,结果表明通风量对CO扩散的影响要远远大于送风温度对其的影响 .基于数值模拟结果对某发动机试验室通风系统进行优化设计 .更多还原

【Abstract】 Based on three-dimensional numerical simulation on the diffusion rationale of confined carbon monoxide jet,this paper analyzes the ventilation volume and the temperature of the supplied air’s influences on the diffusion of carbon monoxide.According to the conclusion that the supplied air is more important,the optimal design of ventilation system for some engine lab is given out.更多还原
