Single Particle Heat Transfer Modeling for Expanded Shale Processing

12 Single Particle Heat Transfer Modeling for Expanded Shale Processing 

The density or specific gravity change of the shale particle to three-dimensional diffusion will result in a three-dimensional expansion. The incremental change in each direction may be calculated independently using the unidirectional expression
