1. 1. CFD Modeling and Optimization of Primary sedimentation tank

   Master-uppsats, KTH/Vattendragsteknik

   Författare :Aibin Zhang; [2017]
   Nyckelord :VOF model; RNG k-ε model; velocity; turbulence; primary sedimentation tank;

   Sammanfattning : In this project, the flow field characteristics of the simplified 2D rectangular primary sedimentation tank in Syvab wastewater treatment plant were achieved by a transient water-air two phases finite-volume method, applying Volume-Of-Fluid (VOF) model. RNG k-ε turbulence model was also employed to calculate the turbulent kinetic energy and its dissipation rate. LÄS MER

   Sammanfattning : The main purpose of this thesis was to simulate the three-dimensional flow patterns in tanks for water storage. The practical intentions of the simulations were to identify water-quality problems related to insufficient water exchange. The water storage reservoirs at Norra Ugglarp in South Sweden were investigated as a special case study. LÄS MER
