This study deals with the modelling of the thermomechanical phenomena due to
friction effects during granular flow. A two-dimensional model using the discrete
element method (DEM) and taking into account the contact detection and heat
transfers between grains has been developed. Through this study, we have modelled
the heat transfer by conductance and the energy dissipation by friction into a
granular medium. This modelling enables better understanding of the phenomena at
the contact point between grains as well as the energy dissipation by friction of a
great number of grains in motion. The validity of the proposed model has been
studied by considering some numerical simulations in quasistatic and dynamic
regimes.
