A novel snow transport model for analytically investigating effects of wind exposure on flat roof snow load due to saltation

Critical Review of Modern Numerical Modelling of Snow Accumulation on Roofs With Arbitrary Geometry

“…Obviously, this is due to the imperfection of existing models and methods and lack of qualitative achievements in their development. Since about 2014, there has been an increase in the number of works on the numerical modelling of snow accumulation and snow transport from China [23,36,37,44,45], supported by government grants and aimed at upgrading building codes, which will probably lead to verified methodologies emerging soon. Few Russian scientific works on the topic [47,48,49,50,51], on the contrary, are mostly derivative in nature, despite the problem of calculating snow loads on the roofs of buildings and structures with arbitrary geometry in our country being way more relevant due to the features of the climate.…”

“…for the flow around a cube [12,20,32,33] or a solid fence [11,20]. Some scientists have tried to apply the models to real-life problems, such as the accumulation of snow on the roofs of buildings [22,34,35,36,37,44] or around buildings or landscape formations [16,17,38,39,40,41,45]. In each case, it was necessary to calibrate the models for the specific conditions of the given problem and to individually select the parameters, although even then minimizing the divergences with observations was not sufficient to speak of an "accurate" reproduction of "real" snow deposits [19].…”
