摘要
通过开展地下水电站无压尾水洞引风降温模型的综合试验,测出了不同风速,不同尾水流速情况下空气、尾水及洞壁的温度,得到各种工况下的换热系数,经过对比分析得出引风速度、尾水流速对无压尾水洞引风降温效果的影响。
Through carrying out the comprehensive test of the air-induced cooling model of the non-pressure tailrace in the underground hydropower station, the paper measures the temperature of the air, the tailrace and the tunnel wall in the condition of the different wind speed and the different flow velocity of the tailrace, obtains the heat transfer coefficient in the different condition, obtains the influence of the air-in- duced speed and the flow velocity of the tailrace to the air-induced cooling effect of the non-pressure tailrace.
