Numerical methodology for spontaneous wrinkling of centrally ignited premixed flames - linear theory

An improved embedded-manifold/Navier-Stokes numerical methodology is developed to simulate the propagation of premixed flames within the context of the hydrodynamic theory. The method is computationally tractable, permitting calculations to not only be extended to larger physical domains but also to...
