Notes:
An instability is proposed that can lead to channel formation during the regeneration of monolithic diesel-particulate filters. This instability, which occurs during the transport-controlled combustion of the soot bed, is compared to a kinetically driven instability by using a numerical model for channel growth. Both mechanisms are shown to be important and may lead to higher thermal stresses in the filter wall. It is suggested that both mechanisms can be controlled by the ratio of the filter-plate to soot-bed flow resistance, lateral heat transfer, and other design parameters.
