Outdoor Test of Wind-Drifted Snow Distribution around a Cube

This paper presents the results of an outdoor investigation of wind-drifted snow distribution around a cube. The test was performed in a simple outdoor wind tunnel at Harbin in January 2009. Velocity distribution around the cube and pressure coefficient on the cube surfaces are also simulated with computational fluid dynamics (CFD). The simulation is based on homogenous two-phase flow theory, where the flow field is predicted by solving Navier-Stokes equations for transient, incompressible viscous flow. The inlet profiles of the simulation adopted data got from wind tunnel. Comparison between the test result and that of simulation shows that velocity is closely related to the snow distribution.
