Energy fluxes in snow avalanches / O. Buser, P. Bartelt.
Title: | Energy fluxes in snow avalanches / O. Buser, P. Bartelt. |
Author(s): | Buser, O. Bartelt, P. |
Date: | 2008. |
Language: | Russian transliteration entered into original records using BGN/PCGN 1947 romanisation of Russian; Cyrillic text in MARC 880 field(s) reverse transliterated from this by automated process; BGN/PCGN 1947 text then upgraded to Library of Congress romanisation. |
In: | Materialy Gli︠a︡t︠s︡iologicheskikh Issledovaniĭ. (2008.), Vol. 105 (2008) |
Abstract: | Presents description of snow avalanche dynamics at level of macroscopic properties of granular system, aiming at reduced description of rheology that accounts for granular interactions without oversimplified lumping into single "effective" viscosity or "turbulent" friction parameter. Describes simple shear motion of avalanche by superimposing horizontal and vertical random velocities of granules on laminar steady flow fields. Presents: characterization of granular effects by random kinetic energy of particles; introduction of effects into pre-existing constitutive model; and comparison of velocity and random kinetic energy profiles with experiments made during two avalanches at Vallee de la Sionne. Discusses insight gained, particularly for avalanches in non-steady states. |
