초록

This study aims at examining the design factors of the air diffuser system in a particular view of field conditions, and thus improving the procedures currently applied to design the system. First, the CFD model is built for an air diffuser system suitable for field conditions of real reservoirs. Then, the design factors, including destratification number, destratification radius and efficiency of the air diffuser system, are analyzed after a series of simulations over various field conditions. The result shows successful correlations of design factors with DN at the condition, and they lead to estimate of the destratification radius and efficiency of air diffuser system based on DN. It is finally concluded that the design factors are improved such that the air diffuser system is suitable for the field conditions of dam reservoirs.
