The universal teardrop shape of the joint probability density function (jpdf) of the second and third invariants of the velocity-gradient tensor disappears in the different flame regions under study. A ‘canonical’ vortex, which affects the fine-scale structure of the turbulent premixed flame, has been identified and analyzed at three times, differing by increments of the order of the Kolmogorov time micro-scale.2016http://zaguan.unizar.es/record/16498010.1007/s10494-015-9686-1http://zaguan.unizar.es/record/164980oai:zaguan.unizar.es:164980Flow, Turbulence and Combustion 96 (2016), 535–546All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
