Test Investigation of Velocity Distribution Considering Snow Particles Participating

Abstract

This paper presents the fitting expressions of mean velocity profile and turbulence intensity for wind-snow coupling conditions. Different materials were adopted to simulate the roughness of saltation snow particles to get the distribution of wind velocity in the simple wind tunnel. Test results indicate that velocity profile obeys the logarithmic distribution; the turbulence intensity obeys power law distribution. The influence height of saltation snow particles to the velocity profile limited to 10 cm above from the bed surface.

Outdoor Test of Wind-Drifted Snow Distribution around a Cube

“…In this paper, the authors present an outdoor test result of wind-drifted snow distribution around a 20 cm cube in a simple wind tunnel. The velocity field got with wind rake in Tongji University [5]is adopted in CFD simulation. The result of simulation is compared with that of outdoor test.…”
