Abstract:
Based on heat and moisture transfer theory,the lumped parameter prediction model of heat and moisture transfer between air and tailrace water,air and tailrace tunnel surface is established by analyzing the performance of heat and moisture transfer process of tailrace tunnel ventilation.The analytical solution of air parameters in tailrace tunnel is presented,and the model is validated by the experiment in laboratory and field test.The air parameters of tailrace tunnel ventilation in a real hydropower station are predicted and analyzed by the model.The results provide the theoretical basis and design guidance for the application of tailrace tunnel ventilation system in hydropower station.
