## Detailed Description

These classes provide transport properties.

## ◆ VelocityBasis

 typedef int VelocityBasis

The diffusion fluxes must be referenced to a particular reference fluid velocity.

Most typical is to reference the diffusion fluxes to the mass averaged velocity, but referencing to the mole averaged velocity is suitable for some liquid flows, and referencing to a single species is suitable for solid phase transport within a lattice. Currently, the identity of the reference velocity is coded into each transport object as a typedef named VelocityBasis, which is equated to an integer. Negative values of this variable refer to mass or mole-averaged velocities. Zero or positive quantities refers to the reference velocity being referenced to a particular species. Below are the predefined constants for its value.

• VB_MASSAVG Diffusion velocities are based on the mass averaged velocity
• VB_MOLEAVG Diffusion velocities are based on the mole averaged velocities
• VB_SPECIES_0 Diffusion velocities are based on the relative motion wrt species 0
• ...
• VB_SPECIES_3 Diffusion velocities are based on the relative motion wrt species 3
