  • Cascading Analysis Using Discrete Element Method in

    Discrete Element Methods have been used extensively in processes involving flow behavior where modeling the individual particles is of particular interest. A rotary cooler is an application of one such process. Although the current analysis can be used to any type of rotary cooler or rotary dryer, this work is focused on the analysis of particles falling from lifters in a planetary rotary ...
