Species Balances

  • Constantine Pozrikidis


We have regarded an inhomogeneous mixture parcel consisting of different species as an instantaneous superposition of single-species parcels that interact by chemical reactions and intermolecular force fields as they move through one other in a flow. Species parcel properties and rates of evolution may be defined and then combined to yield expressions for effective mixture properties as functions of constitution. The diffusive mass flux arises naturally in these equations in terms of the differences between the species and mixture velocities, constituting diffusion velocities.
