Overview
The 'Frictional Heat' API introduces frictional heat effects into your DEM particles within your EDEM simulation. This API calculates the heat generated due to friction and allocates equal heat flux to the interacting elements. An example is also attached that shows the usage of the API.
Prerequisite: EDEM 2025.1 or above
Usage/Installation Instructions:
- Extract the zip file attached. Copy the 'FrictionalHeat.dll' from the 'example' folder to the directory of your EDEM simulation.
- You can add this model in the 'Particle to Particle' or 'Particle to Geometry' interaction of the Physics section.
- Within the settings (cog button) of the model, you can choose which interactions heat must be generated from. If you do not choose a particular interaction, there will be no heat generated from that interaction. You will need to enter a 'Heat Conversion Factor' (between 0 and 1) which will determine how much of the frictional energy is converted to heat.
Post-Requisite:
- Since this model is decoupled from existing heat-related models within EDEM, you will need to choose any other heat related model separately within your simulation. Consequently, you can choose to add the 'Heat Conduction' model for your 'Particle to Particle' and 'Particle to Geometry' interactions, if you need.
- This model calculates the heat flux only. Most users would also wish to understand the change in temperature of the particles. Please remember to add the 'Temperature Update' model in the 'Particle Body Force' of the physics section if you require to calculate temperature changes of the particle due to this heat generation.
