Experiment And Numerical Study On Dynamical Environment Of Nuozhadu Hydroelectric Power Station

The paper is based on experiment, analyzes the heat transfer characteristic of underground workshop. Sets up a mathematical model of unsteady heat transfer of deep underground structure based on the mechanism of heat transfer. Leads the coefficient of response into boundary conditions to make the dynamic problem solved. Draws up corresponding computer program for the heat transfer differential equation and boundary conditions. Using this program simulates the thermal environment in the underground workshop of Nuozhadu hydropower station. The calculation results include indoors average temperature, heat transfer and so on. All of these provide the scientific guideline for the final cooling load and the choice of air conditioner.In the light of the characteristic of Nuozhadu hydropower Station , compares four plans of ventilation and air conditioning system for the plant, according the result, recommends it the best one that air flow is regulated seasonal in the last one.
