Abstract
The experiments on snow drift were carried out using the low temperature wind tunnel at Shinjo Branch of Snow and Ice Studies, NIED in Shinjo, Yamagata Pref. The wind veloctiy profiles were measured by the hot film anemometer and the snow drift flux profiles were measured by the snow paricle counter (SPC). The size distribution of snow particles were also measured by SPC. These results obtained by the experiments show that the higher the measuring position is, the smaller the size of snow particles is. The numerical analyses were made using the non-Boussinesq κ-ε turbulence model and the results were compared with the experimental rersults. The numerical results of the velocity profiles show the typical profile in a boundary layer. The snow drift flux obtained by the numerical analysis agrees well with the experimetal results near the bed. The velocity profle in snow drift is expressed by the log+linear law.
