Fig. 1 Comparison of temperature profiles from numerical results and data from Mamora ( 1993 )
characteristics of experiments are reported in Table 2 . Characteristics of Mamora's
experiments correspond for a 1D homogeneous combustion tube.
Figure 1 shows theoretical and experimental temperature fields in the combustion
tube. At early times, the theoretical front advance slower than the experimental one,
but eventually both profiles match for further times. Nevertheless, the combustion
front width increases with time, meanwhile the experimental front preserves its thick-
ness, leading to substantial errors for long times. In a general sense, the numerical
