In this paper we propose a new level set approach to describe not only a flame's surface but also to the flame's spatial distribution. First. we derived the mathematical formulation for a one-dimensional laminar premixed flame. where the steady flame has a finite thickness depending on the diffusion flux whose physical quantity such as temperature has a relation to index fun... https://www.mariameetsanna.com/product-category/color-extend-magnetics-deep-attraction/
