摘要
采用湍流模型结合组份传输模型,模拟某办公室在自然通风条件下的室内甲醛浓度数值,通过对比分析监测点的实测值与仿真值,并用配对样本T检验方法验证仿真模型的正确性。另通过正交试验的方法,对办公室的结构进行了优化设计,结果表明,调整窗口、门口、办公桌位置,可进一步将办公室甲醛浓度降低40%。文章通过CFD数模拟计算方法研究室内甲醛浓度变化规律对进一步研究有效的技术措施降低室内甲醛浓度提供参考。
By using turbulence model and component transport model, the indoor formaldehyde concentration in an office under natural ventilation is simulated, and the measured and simulated values at the monitoring point are compared and analyzed. The validity of the simulation model is verified by paired sample T-test. In addition, the structure of the office was optimized by orthogonal test. The results showed that the formaldehyde concentration of the office could be further reduced by 40% by adjusting the position of the window, the door and the desk. The paper studies the indoor formaldehyde concentration change rule through the CFD number simulation computation method. It provides the reference for further research effective technical measure to reduce the indoor formaldehyde concentration.
