Description
Summary:The free-boundary problem describing the oscillating dynamics of condensed fuel gasless combustion is studied numerically. In qualitative agreement with recent numerical results established for the model employing the distributed reaction rate, it is shown that one-dimensional flame propagation may undergo highly irregular relaxational oscillations provided the bifurcation parameter (Zeldovich number) is high enough. Increasing the bifurcation parameter leads to an enhancement of the level of fluctuations and a reduction of the average flame speed.
