Estimation of vapor velocity, vapor density and vapor temperature in a snow pack and its application in avalanche forecasting
In the proposed study, fluid flow and heat transfer of water vapor in a snow pack are studied. Variation of flow parameters such as velocity, density, dynamic pressure and temperature of vapor have been observed for various snow densities and vapor viscosities in the snow pack. The results have been compared with available empirical results that are for the growth of grain size at various heights in snow pack. The advantage of the present model in using for avalanche predictions has been highlighted. (C) 2012 Elsevier Ltd. All rights reserved.
