CFD simulation and performance comparison of surface aerator for deep aeration
|
Abstract:
The research and development of deep aeration by using down umbrella surface aerator are important for reducing investment and land occupation of the construction of wastewater treatment plants. This paper presents the numerical simulation of 3 type aerators with different structure by using CFD software. The stirring effects and power efficiency of each type aerator are analyzed and compared between the 3 type aerators. Experiment in small tank was carried out to confirm the CFD simulation.
