The heating of soil during fires may result in organic matter loss. The ratio of combustion enthalpy of soil organic matter to the alpha-beta quartz transition enthalpy can be used to compare heated and unheated soil. This eliminates the need to weigh samples and is insensitive to differences in water content between heated and unheated soils, making possible in-situ applications in field sites.
In this study, a three-dimensional two-phase flow model based on the kinetic theory of granular flow (KTGF) was used to predict the behavior of a gas-solid fluidized bed. The model is based on a Eulerian description of the two phases, gas and particles, and is composed of a set of mass conservation and momentum equations for each phase.READ MORE
