通风对狭长空间温度分布规律影响的数值模拟与实验研究
Numerical simulation and experimental study of influence of ventilation on temperature distribution in long and narrow space
摘要：
对非常温工况的狭长空间，采用通风的方式进行降温是行之有效的。通过数值模拟研究了不同的通风量对狭长空间温度分布的影响规律，根据相似准则建立了实验台，并将模拟结果与实验结果进行了对比，结果表明计算值与实验值吻合较好，证明了用模拟的方法研究类似的工程问题是可行的。

Abstract：
Mechanical ventilation is effective in lowering the temperature in long and narrow space at non-normal temperature. Simulates the influence of different ventilating rates on the temperature distribution. Establishes a test-rig based on the similitude laws. The simulation results are in quite good agreement with that of the experiment by comparison. This validates the practicability of using simulation methods to study similar engineering problems.
