Numerical simulation of thermodynamic performance in a honeycomb ceramic channel
Abstract
In order to understand the thermodynamic performance in honeycomb ceramic channel, three dimensional numerical simulation was carried out by using FLUENT.Effects of mass flow rate, solid heat capacity, and reversal time on temperature efficiency were investigated. Results show that with the increasing mass flow rate the temperature efficiency decreases linearly, and the pressure drop increases linearly in each half-cycle.For computed cases the effect of solid heat capacity on the temperature efficiency is ignorable. With the increasing reversal time, the temperature efficiency decreases slowly in bed heated period, and it is almost not influenced in bed cooled period.References
