At time t < 0, a steady motion of a chemically reacting dilute binary mixture of a gas exists in a long cylindrical porous pipe, such that the steady‐state velocity component and the gas concentration are given by ( u s , v s , O) and c s in cylindrical polar co‐ordinates ( r , ø, z ). When t = O, a constant pressure gradient is applied at one end of the tube. If the inertia terms are neglected, a Laplace transform and a finite‐difference scheme are employed to solve for the transient flow ( u, v. w ) and c. The time required to achieve a steady state is different for w on one hand, and for u, v and c on the other hand.
