Abstract: The clustering of marker nodes in regions of high curvature and the topological change of flame fronts have long been the main difficulties that limit conventional Lagrangian front-tracking methods from wide use in the modelling of turbulent premixed flame propagation. In this work, we introduce a robust numerical method called contour advection with surgery (CAS) to simulate, in wholly Lagrangian terms, the propagation and advection of the flame front in ambient turbulent flows. With a novel technique known as contour surgery, CAS can properly treat topological changes of the flame front. We apply CAS to study the problem of the two-dimensional turbulent premixed open V-flame. The computed velocity statistics and the estimated flame surface density are compared with corresponding laboratory measurements, and show satisfactory agreement for the trends and basic features. In addition, this method is found to be able to capture the counter-gradient diffusion effects and to reproduce the trends of distributions of local flame front curvature observed in experiments.
