Abstract

A concentrated heat source moves at constant speed through a diffusive medium which can support an explosive reaction. If the conditions are such that a blow-up would occur for a stationary source, it is shown that there is a critical speed above which the explosion can be avoided. The reactive-diffusive medium is assumed to be contained in an infinitely long tube of general cross-section. Both the cases of Neumann and Dirichlet boundary conditions imposed on the tube surface are considered.
