Overview

Attached to this post you’ll find an example that uses a body force to update the particle temperature based on a temperature field, as a simple means of modelling convection. This is a one-way coupling, meaning the temperature field is static and not changing based on the particle temperatures.

 

Usage/Installation Instructions

Model is written it in such a way that the inputs in the preference file are:

·         the thermal conductivity of the fluid

·         the heat capacity of the particle

·         the Nusselt number

Model uses the same names for the Heat Flux and Temperature custom properties that EDEM does, meaning that the this API plugin adds to any existing values, making it compatible with both the particle-particle and particle-geometry heat conduction models that are in-built to EDEM. The example EDEM deck has all 3 heat mechanisms (p-p conduction, p-g conduction, field convection) in place to demonstrate this, so that the field is heating all the particles but the walls are cooling those touching the geometry.
