Below are several 1-d flame models run with FLASH. These are mixing C/O flames, and use the Caughlin and Fowler (1988) C+C reaction rate. Oxygen is not burned here, just passively advected. These models were used in measuring the response of flames to curvature, as reported in Dursi et al. 2003, ApJ, submitted.

The problem is setup with C/O in the left side of the domain, and Mg in the right. The left boundary is inflow, with a speed that is ~ the laminar flame speed. The right boundary holds the pressure constant. The flame speed is computed as the front speed (measured by differencing the front position in two different timeslices) - the inflow velocity. Thermal widths are also reported, as the distance between the point where the temperature is 10% above the ambient temperature and 10% below the peak temperature (this is referred to the "10/90" flame width in Dursi et al. 2003, ApJ, submitted).
