We present a continuum approach to model segregation of size-bidisperse granular materials in unsteady bounded heap flow as prototype for modeling other time varying flows. In experiments, periodically modulated feed rate produces stratified like that which occurs due intermittent avalanching, except with greater layer-uniformity and higher average rates. Using an advection-diffusion-segregatio...

Abstract This paper reports the findings of a comprehensive field investigation on flow through mountain gap subject to range stably stratified environmental conditions. study was embedded within Perdigão campaign, which conducted in region parallel double-ridge topography with ridge-normal wind climatology. One ridges has well-defined (col) at top, and an array situ remote sensors, including n...
