Explorations into thermodynamic analogies and critical points in reference to gas-solid transport
The use of analogies to explain transport processes is not new, nor is the idea of borrowing concepts from thermodynamics and applying them to transport phenomena. Experimental data from several investigations, where the solid voidage has been determined experimentally, have been analyzed to test the ability of a cubi van der Waals equation to represent the solid flow, gas flow, and voidage. Using the van der Waals format, phase diagrams have been constructed for a number of particulate systems. From this information, the critical properties of the solids can be found. A generalized reduced-properties plot seems to correlate the existing data satisfactorily. The same approach is pursued to interpret the pressure drop data.
