Discrete Element Modelling (DEM) is a computational technique that allows particle flows in various types of equipment to be simulated. It has been used extensively in the simulation of mills (Cleary, 1998, Cleary, 2001a, Cleary, 2001b, Cleary, 2001c, Cleary, 2004, Cleary et al., 2003, Morrison et al., 2001).DEM simulation involves following the …
Performing Dimensional Analysis. The use of units in a calculation to ensure that we obtain the final proper units is called dimensional analysis. For example, if we observe experimentally that an object's potential energy is related to its mass, its height from the ground, and to a gravitational force, then when multiplied, the units of mass ...
