发动机试验间通风效果三维数值模拟

Three-dimensional Numerical Simulation of the Ventilation Effect in Engine Test Room

借助CFD技术,对两种典型的基于暖通设计手册及经验设计的发动机试验间通风方案进行数值模拟,得到了发动机试验间内温度分布情况、气流组织形式和空气流速。通过对比两种典型通风方案的三维仿真结果,确定了通风方案二的通风效果更好。

With the help of CFD technology, two typical ventilation schemes of engine test room designed based on HVAC design manual and experience are numerically simulated, temperature distribution, air flow pattern and air velocity within the engine test room are obtained. With comparing the three-dimensional simulation results of the two typical ventilation schemes, and ventilation effect of ventilation programⅡis proved better.
