Abstract: Based on the fundamental equations, the incompressible, neutrally stratified, horizontally homogeneous, steady, and barotropic atmospheric boundary layer was simulated by the modifying parameters of a k-ε model. Through the three steps of pre-simulation, main simulation, and near-ground physical quantities adjustment, the method of self-sustaining for a wind field was discussed. The studies show that: by the modifying parameters of a k-ε model, the consistent simulation results with the measurement data are obtained. The physical quantities can be self-sustained well when the wind profiles obtained from the pre-simulations with a few meshes are applied to main simulations. More ideal self-sustained results can be achieved by the near-ground physical quantities adjustment with the Fixed Values operation in ANSYS Fluent.

Key words: computational fluid dynamics, atmospheric boundary layer, self-sustaining, k-ε model, Coriolis force
