曝气池内气液流态的实验分析和数值模拟

Experimental Analysis and Numerical Simulation of the Flow State of Gas-liquid in Aeration Tank

曝气池中的流动是一种复杂的气液两相流动,运用FLUENT软件对曝气池内气液两相流动进行数值模拟,并通过实验验证数值模拟结果的准确性.结果表明:运用FLUENT软件进行数值模拟的数学模型基本准确,实验与数值模拟结果基本吻合.

The flow in aeration tank is a complex two-phase flow of gas-liquid. In this paper,the two-phase flow of gas-liquid in aeration tank is simulated by FLUENT software,and the accuracy of numerical simulation is verified by experiments. The results show that the mathematical model of numerical simulation by using the FLUENT software is basically accurate,and the experimental results are basically consistent with the numerical simulation results.
