We present, compare and discuss results of three-dimensional hydrodynamic simulations of the thermonuclear burning phase in Type Ia supernova explosions. Our emphasis is on the validation of the underlying numerical model as well as on the investigation of the influence of the initial conditions, i.e., the flame geometry inside the white dwarf at the onset of the thermonuclear explosion, its density and its chemical composition on the outcome of the simulations. In particular we investigate whether the obtained results of such `parameter-free' models are in agreement or in conflict with observational constraints, such as the the nickel masses and explosion energy. We find that our models predict most properties within their observed ranges.
