Abstract

© Springer Nature Singapore Pte Ltd. 2019. Aeration is an effective method to repair old landfills and reduce the post-closure charge. Before designing the aeration systems, reliable prediction of aeration systems performance is important because operators could optimize the system based on it. This study proposes a three-dimensional CFD model of vertical aeration systems using ANSYS Fluent platform. Multiphase flow, multicomponent transports and biochemical reaction are considered to simulate the hydro-biochemical process when aeration occurs in aerobic landfills. This model was verified by experimental data successfully. The results focus on the influence of aeration frequency and well depth in terms of intermittent aeration in landfills.
