Simulation of a premixed turbulent flame by a conservative level set method. (English) Zbl 1321.80005

Summary: The premixed turbulent V-flame is numerically simulated in this paper. The technique used in C. K. Chan et al. [Int. J. Eng. Sci. 41, No. 8, 903–916 (2003; Zbl 1211.80040); Int. J. Numer. Methods Eng. 48, No. 4, 613–627 (2000; Zbl 0966.80008)] was based on the random vortex method and the conventional level set method. However, this paper is an improvement of the previous technique by using a conservative level set method. The new algorithm uses a bi-cubic interpolation process together with Newton’s method to reconstruct the velocity field to improve the conservation of the level set method. The numerical example in this paper indicates the efficiency of the new method in solving the problem of turbulent premixed V-flame by comparing the results with available data.
