Numerical Simulation of Snowdrifts and Snow Transport in Civil Engineering
10
2019
Calculation of snow loads on the surfaces of unique buildings and structures is a complex problem, which requires correct accounting of snowdrifts and snow transport to be solved. Although ubiquitous, the wind-tunnel experiments are known to have certain flaws in this case, such as the precision loss due to scaling, the use of substitute materials instead of snow, and the conditions & parameters aren’t always easy to control. Thereby, the numerical methods appear to be relevant. Notwithstanding the lack of noticeable progress in the snowdrifts modeling, which, adding the practical importance, still remains one of the problems in the computational aerodynamics, the developed models allow to achieve plausible results. In this paper, a numerical method of the calculation of snow loads through the modeling of snowdrifts and snow transport using the Naaim et. al model is proposed. ANSYS is used for the implementation. The method is verified by solving a test problem and a normative problem. Despite the results being in accordance with the experimental data, the imperfection of the model used and the necessity for new, probably hybrid methods of modeling to be developed are emphasized.
