    A new method to implement comminution functions into DEM simulation of a size reduction system due to particle-wall collisions

    The ability to design a size reduction system prior to full scale experiments and to optimize existing systems has long been a goal of designers. Such a design and optimization could be achieved by correctly s...

    The effect of internal particle heat conduction on heat transfer analysis of turbulent gas–particle flow in a dilute state

    In many cases the conduction mechanism inside a particle can not be ignored (large particles, low thermal conductivity and high porosity) during turbulent gas–particle flows. However, the accurate solution mig...
