This thesis examines the transient response of a packed bed heat
regenerator when heated from an initial uniform bed temperature. Very large
(1700 K) temperature differences were studied as well as the effect of
simultaneous chemical reaction in the gas phase.
First the effects of temperature on physical and transport properties
were studied in detail in the absence of a reaction. Models with compressible
flow were compared with conventional models with constant properties and
incompressible flow. Several measures of the regenerator's response to a step
change in inlet gas temperature were calculated to characterize the spread of
the temperature front. Variances of the spatial derivative of the gas
temperature profile and the time derivative of the product gas temperature
were used to evaluate thermal efficiency.
The effects of an exothermic homogeneous gas phase reaction in the
regenerator process were also studied. Several simple kinetic schemes and inlet
conditions were simulated and the profiles of reaction rate and conversion as
well as temperature were analyzed. / Graduation date: 1993
