Plug-Flow Reactor (PFR) Assumptions in modeling the PFR Steady state, steady flow. • No mixing in the axial direction No mixing in the axial direction. No mass diffusion or heat transport in the axial direction. Uniform properties perpendicular to the flow. Frictionless flow. Ideal gases. School of Mechanical Engineering, Purdue University
