Convection in Drying and Freezing Ground
Mir Faizal, Stephen Peppin
In this paper we analyse the drying of a soil composed of particles, water and solute impurities, and study the occurrence of convective instabilities during evaporation. We find t…
Ice-lens formation and geometrical supercooling in soils and other colloidal materials
Robert W. Style, Stephen S. L. Peppin, Alan C. F. Cocks +1
We present a new, physically-intuitive model of ice-lens formation and growth during the freezing of soils and other dense, particulate suspensions. Motivated by experimental evide…
Dynamics of colloidal particles in ice
Melissa Spannuth, S. G. J. Mochrie, S. S. L. Peppin +1
We use X-ray Photon Correlation Spectroscopy (XPCS) to probe the dynamics of colloidal particles in polycrystalline ice. During freezing, the dendritic ice morphology and rejection…
Onsager reciprocity in premelting solids
S. S. L. Peppin, M. Spannuth, J. S. Wettlaufer
The diffusive motion of colloidal particles dispersed in a premelting solid is analyzed within the framework of irreversible thermodynamics. We determine the mass diffusion coeffic…
