【摘要】 对描述自然通风逆流式冷却塔对流换热过程的三变量模型,利用中心差分法进行求解,计算过程利用VC++语言实现;对承德滦河电厂2号自然冷却塔进行模拟,将计算结果与实验数据进行比较,相对偏差较小,证明此程序是可靠的;在计算结果的基础上,对该冷却塔不同工况进行冷却性能评价,得出结论是该冷却塔运行状况良好。图1表2参5更多还原

【Abstract】 The three-variable model describing the heat convection process in the natural ventilation wet cooling tower is computed using central difference method, and realized with the language of VC++; the natural cooling tower of Luanhe power plant in Chengde city is simulated, the calculation result is compared with the experimental results, relative deviation is small, so the software is reliable; the evaluation of the cooling power is carried on the basis of the calculation results, the results indicate that the cooling tower is running in good state.更多还原
