Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | In thermal flow-reversal reactor operations, honeycomb
ceramic regenerators are exposed to
thermal shock load. In this study, numerical simulations
of the temperature and thermal stress
distributions of honeycomb ceramic regenerators
are carried out using the CFX software.
Temperature variations with time are calculated
first for honeycomb ceramic regenerators with
holes of different shapes. Then, thermal stress
distributions of regenerators are analyzed with
different structural and operational parameters.
The analyses show that the thermal stress of honeycomb
ceramic regenerator depends on the
shape of holes, porosity and wall thicknesses.
This study provides a theoretical basis for optimization
of honeycomb ceramic regenerators. |
