Abstract
Full scale Ningxia super high-rise steel TV tower (NXTVT) model is established in the numerical simulation to investigate the flow field around it. And then, the UDF program of mean wind section plane, turbulence kinetic energy and turbulence dissipation rate were compiled. The flow fields under these two typical inflow conditions, 30 degree is chosen as the field measurement data. The results show that both the RNG model and the Realizable model can simulate the distribution rule and similarity. Both can give reasonable turbulence kinetic energy distribution in the region of windward sharp edge, where flow separation occurs. Subsequently, the mean pressure field with certain precision can be obtained in the highly turbulent negative pressure region.
