A laminar flow field in which the velocity profile may be distorted in a predictable manner was achieved in a 7‐cm porous pipe with uniform wall injection over the ranges of variables: 0≤ λ ≤ 2, 200 ≤ N Re ≤ 800 and 0.05 ≤ X ≤ 0.2. A mathematical model was then developed to describe the concentration distribution of a gaseous tracer discharged continuously from a finite source in this particular flow field. Experimental measurements taken over the same ranges of variables verified the validity of this model. The result from this study may be useful in the water desalination process using reverse osmosis.
