Fluctuations in the number of particles (or droplets and bubbles) are observed in experiments of multiphase flows, and these also manifest as fluctuations of the dispersed–phase volume fraction. The intensity of these fluctuations is characterized using a mathematical description based on second–order statistics. The intensity and range of fluctuations in the clustering regime of a granular gas...

We show that a micropolar fluid model successfully describes granular flows on a slope. Micropolar fluid is the fluid with internal structures, and the coupling between the rotation of each particle and the macroscopic velocity field is taken into account; it is a hydrodynamical framework suitable for granular systems which consists of particles with macroscopic size. It is demonstrated that th...

Biomass as a clean and renewable source of energy has immense potential to aid in solving the crisis world. In order accurately predict fluidization behavior biomass particles using Eulerian–Eulerian approach kinetic theory for granular flows (KTGF), employing appropriate models that adapt irregularly shaped can precisely interaction between is crucial. this study, effects varying radial distri...

When a granular mixture involving grains of different sizes is shaken, sheared, mixed, or left to flow, grains tend to separate by sizes in a process known as size segregation. In this study, we explore the size segregation mechanism in granular chute flows in terms of the pressure distribution and granular microstructure. Therefore, two-dimensional discrete numerical simulations of bidisperse ...
