MARC recordEffects of support structure porosity on the drift accumulation surrounding an elevated building / Arnold Song, Robert Haehnel.
| Title: | Effects of support structure porosity on the drift accumulation surrounding an elevated building / Arnold Song, Robert Haehnel. |
| Author(s): | Song, Arnold. Haehnel, Robert. |
| Date: | 2012. |
| In: | ERDC/CRREL Technical Report. (2012.), TR-12-7 (2012) |
| Abstract: | Examines effects of porosity of substructure used to elevate buildings in Antarctica on drift accumulation. Compares snowdrift evolutions observed using scale model of Amundsen-Scott Station with field surveys, reporting good agreement when applying Lever and Haehnel's time scaling. Reports wind tunnel investigation of snowdrift accumulation and numerical simulations of flow around prototypical elevated building. As substructure porosity increases, total drift volume decreases and becomes more concentrated upwind of building. For low porosity, separation bubble that can form upwind of building appears to direct particles over region of subcritical shear stress and impede growth of upwind snowdrift. Porosity and ground-based clutter also affected rate of drift encroachment. Suggests that careful design could extend building life by two or more years. |
