Simulations show that the turbulent flame speed grows exponentially, reaches approximately 30% of the speed of sound, and then declines as the large-scale turbulence is frozen by expansion. The freezing of turbulent motions appears to be a crucial physical mechanism regulating the rate of deflagration in SNIa.
