NUMERICAL SIMULATION OF SNOW DRIFTING AROUND BUILDING MODEL

Based on the Euler-Euler method, the Mixture model is used to simulate the snow drifting around a building model by means of Computational Fluid Dynamics (CFD) software —— FLUENT. During simulating, the Finite Volume Method and SIMPLE technology (Semi-Implicit Method for Pressure-Linked Equations) have been used. Saltation as well as suspension are taken into consideration. Firstly, the snow drifting around a snow fence is simulated. Through comparing different turbulence models, it can be proved that the k-kl-ω model had good suitability and effectiveness. Then the snow drifting around a cube model is simulated. Compared with field measurements, the computational results of snow distribution are consistent with the real-scale field measurement that validates the numerical simulation effectiveness.
