説明
A numerical analysis of snow drift has been carried out. The results were compared with experimental snow drift data in the low temperature wind tunnel at Shinjo. The numerical model is based on the non-Boussinesq approximation in which the density is a function of volumetric concentration of snow particles. The model consists of the air continuity eguation, the mass snow particle conservation equation, the Reynolds equation the turbulence kinetic energy equation an equation of the viscous dissipation rate. Using several sets of parameters; i.e. the slope angles, the near bed concentrations and the diameters of snow particles, the model calculations are carried out. In the experiment, snow drift was generated in a wind tunnel. The velocity profile was measured using a hot film anemometer and snow particle flux was measured by a snow particle counter (SPC). The numerical solutions can explain these profiles well if we choose appropriate values of parameters included in the model.
