Computational Analysis of Gas Flow and Heat Transport Phenomena in Monolithic Structures for High Temperature Processes
(2005) ASME Summer Heat Transfer Conference, 2005 p.87-96- Abstract
- High-temperature catalytic processes such as partial oxidation
of Methane (POX) and steam Methane reforming (SMR)
may benefit from use of reactor systems using monolithic honeycomb
structures. Hereby, process performance is enhanced
through more efficient heat transfer and considerable smaller reactor
foot-prints than for conventional reactor concepts. Compact
ceramic heat exchange structures may also be an interesting
option for increasing the energy efficiency of high temperature
processes in general. One example is single cycle turbines where
these structures can be used as recuperators. The purpose of
this paper is to describe modelling of gas... (More) - High-temperature catalytic processes such as partial oxidation

this paper is to describe modelling of gas flow pattern and heat
transfer in reactors and heat exchangers with monolithic based
structures. This technology is currently under development in a
partnership of European companies and academia, with financial
support from the EC and Swiss Government. The mathematical
model developed for heat transfer and flow maldistribution
has been used for counter-current checkerboard channelarrangement.
Pressure drop has been analyzed both experimentally
and numerically (computation fluid dynamics, CFD). Power
density has been shown to depend on various reactor parameters.
Channel geometry, inlet gas temperature difference and
channel wall thickness have been calculated to find the influence
on power density. (Less)
