Spherically Symmetric Transport

Model ID: 8481

This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two space coordinates to result in a 1D problem that can be computed fast with small memory requirements. The model of the transient heating of a magnetite ore pellet shows a general approach to modeling spherically symmetric transport problems using a 1D geometry.
