Abstract

We present a versatile three - dimensional two - phase model for simulating snow drift relocation around buildings utilizing deflection fins of various shapes and sizes. The first phase involves numerically obtaining the air velocity profile around the building and fin using a velocity - pressure Navier - Stokes algorithm, while the second phase involves direct classical simulation of snowfall with particle - particle, particle - surface and one - way particle gusting wind interactions introduced to control accumulation, erosion, clumping and drifting. Because the simulation technique is direct, it is potentially useful for storms and surfaces with widely varying conditions. We are also able to consider the effect of crosswinds.
