Wind effects for the accumulation of model snow behind a fence

Abstract

This paper describes wind effects for the accumulation of snow particles formed behind a 2D-fence. Wind tmnel tests that used model snow particles are carried out to examine the relationship between the accumulation of snowparticles and the shear stress behind a fence.
The activated clay particles are used to simulate snow particles . The shear stress is measured by using a shear stress sensor that improved the hot-film anemometer . The experiment shows that the accumulation distributions of model snow particles and shear stress are almost similarity. This paper proves a fact that the shear stress is important for the evaluations of snow drifting behind a fence.
