Aj. Rankin et al., ANNULAR-FLOW IN A CATALYTIC MONOLITH REACTOR - THE SIGNIFICANCE OF CENTERLINE PROBE TEMPERATURES, Chemical engineering research & design, 73(A2), 1995, pp. 110-121
The influence on the flow and temperature distribution of a coaxial th
ermocouple probe inserted in a single channel catalytic monolith react
or is investigated. Both the case of an insulated reactor and a reacto
r installed in a furnace are studied. It is shown that for a moderate
to high wall temperature (700-1000 K) the influence of radiation on th
e measured temperature is significant. For laminar flow in a relativel
y large diameter reactor, significant radial temperature gradients can
develop. The reaction in such a case has a strong tendency to become
mass transfer controlled.
