摘要
在分析冷却塔构成的基础上 ,建立了描述冷却冷却塔风筒内流场分布的数学模型 ,进而利用MATLAB语言求出了偏微分方程组的数值解 ,绘出了风筒内的流场。经研究发现 ,在风筒的中心处 ,存在一个空气倒吸的区域。最后 。
Based on the analysis of the configuration of cooling tower, the mathematical model of describing the airflow in the air pipe of cooling tower is put forward.Then,the numerical value to the partial differential equations group in the mathematical model and the velocity field in the wind pipe of the cooling tower is simulated. As the result of the research, there is flow reversal phenomenon in the region of the center of the air pipe. At last,the measure to eliminate flow reversal is brought forward.
