Summary
The problem of
numerical study of an
one-dimensional
heat wave
propagation model in
the case of
two consequent
exothermic
reactions in a catalytic
fixed bed is
considered. We
describe an
efficient algorithm
based on Godunov's
orthogonal
factorization method
and Newton's
method. Some
recommendations are
given for
construction of
initial approximation.
In addition,
influence of key
physical and
chemical parameters
on the heat
wave properties
is studied. |
