Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
We present results of fully compressible Navier-Stokes simulations of pulsating flame instability in two dimensions using single-step, first-order Arrhenius kinetics. Model parameters correspond to Ze = 9:5, Le = 10, and flame Mach numbers M between 4:62 × 10 and 2:31 × 10. The results show that the pulsating instability in two dimensions creates three types of transverse waves: spontaneous waves, deflagrations, and detonations. All three types of waves can coexist for the same reactive system, but transverse detonations become more likely as M increases. They propagate inside the large preheat zone of the pulsating flame and do not spread into cold material.
