不同池形中推流搅拌器功率消耗的数值模拟
Numerical simulation of mixer power consumptions in different ponds
摘要
Abstract
Four different ponds were simulated by FLUENT 6.0,using unstructured-tetrahedron grid and MRF technology with k-ε turbulence model and SIMPLE algorithm. In urban wastewater treatment, rectangular pond, circular pond, evolution pond and sudden change pond were simulated. The flow velocity fields in the ponds were analyzed, the powers were studied, and the performances of these ponds were forecasted. Results show that mixer′s power consumotion is the smallest in the evolution pond, in the sudden change pond the fluid flow is the worst, and in the circular/ evolution pond the fluid flow is better. The circular/ evolution ponds are suitable for the mixer.关键词
