摘要
提出新型波纹板导流墙氧化沟结构,并基于N-S方程和k-ε紊流模型,采用有限体积法,对新型波纹板导流墙氧化沟的水流流态和水流速度分布进行数值模拟。同时与无延长导流墙和平板导流墙的数值模拟进行比较,研究结果表明:新型波纹板导流墙对降低氧化沟隔墙背后的水流低速区范围和改善污泥沉积有促进作用。
Based on the Navier-Stokes equations and the k-ε turbulent flow model,using finite volume method,a new corrugated plate structure for an oxidation ditch is proposed and the flow pattern and flow velocity distribution are calculated by numerical simulation,which are compared with those of a non-extended guide wall.The results show that the new corrugated plate guide wall can reduce the low water flow areas behind wall for the oxidation ditch and improve the role of eliminating sludge deposition.
