Experimental and numerical study of heat generation by energy dissipation in a rotating drum filled with particulate material

Resumo

This work aims to investigate the generation of heat by dissipation of mechanical energy in particulate
flows. The behavior of material in a rotating drum is considered in experimental and numerical analyses. In the
physical experiments, the temperature of the particles inside the drum was monitored by means of infrared
thermography and the influence of rotation speed and filling ratio was explored. The experimental data were later
used to calibrate numerical simulations using the Discrete Element Method (DEM). The numerical results were
then analyzed to gain more insights into the mechanisms of heat generation.
