Approximating 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 computated 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.
