Catalytic reactor, porous medium flow.
The motion of a dilute binary mixture of a chemically
reacting fluid in a porous channel is considered in this
study. The porous medium is composed of little spheres
with a coating of a catalytic material. The permeability of
the porous medium K is assumed to vary as
0 1 where d*
is some constant parameter and
y is the non-dimensional distance between the two plates.
The resulting, mixed ordinary partial differential non
dimensional equations which govern the flow are solved
analytically and numerically, subject to appropriate
boundary conditions assuming a fully developed flow.
Results obtained for Sc = 0.24 corresponding to hydrogen,
show that irrespective of the wall concentrations 0Γ and
, the flow is in the desired direction.1Γ
