We present a new way of modeling deflagration fronts in reactive fluids, the main emphasis being on turbulent thermonuclear deflagration fronts in white dwarfs undergoing a type Ia supernova explosion. Our approach is based on a level set method which treats the front as a math. discontinuity and allows full coupling between the front geometry and the flow field (Smiljanovski et al., 1997). With only minor modifications, this method can also be applied to describe contact discontinuities. Two different implementations are described and their phys. correct behavior for simple test cases is shown. First results of the method applied to the concrete problems of type Ia supernovae and chem. H combustion are briefly discussed; a more extensive anal. of our astrophys. simulations is given in Reinecke et al. (1998).
