摘要

利用有限体积法对温湿度测定箱中不同直径的三圆柱绕流进行了数值模拟。通过在测湿球温度铂电阻前端设置速度参考点,并考虑铂电阻不同的布置方式和不同的风速,着重研究了风速仪的布置对测湿球温度铂电阻周围风速场的影响。结果表明风速仪的布置会造成湿球温度铂电阻周围风速呈周期性振荡,尾流效应主导了圆柱间流动的相互作用。
        The finite volume method is used to simulate the flow around three cylinders with different diameters in a temperature and humidity measuring box. By setting the speed reference point at the front of the measuring wet bulb temperature platinum resistance and considering the different arrangement of the platinum resistance and the different wind speed,the influence of the arrangement of the anemometer on the wind velocity field around the measuring wet bulb temperature platinum resistance is emphatically studied. The results show that the arrangement of the anemometer will cause the wind speed around the measuring wet bulb temperature platinum resistance to oscillate periodically,the wake effect dominates the interaction between the cylinders.
