Conductive Interactions of a Wrinkled Flame with a Cold Flat Burner
Abstract We study the dynamics of a wrinkled flame held downstream of a cold, isothermal, flat burner The analysis is conducted in the framework of a thermal diffusional flame model. An Arrhenius rate with a large activation temperature and a single reactant with Lewis number unity are postulated We show that the nonlinear evolution equation for the front shape and position is no longer local, neither in time nor in space, when the flame is sufficiently close to the burner surface.
Abstract In this letter, we report clear correlations between the glass transition temperature Tg, the crystallization temperature Tx, the Curie temperature TC and the electronegativity based on statistically analyzing more than 200 kinds of soft magnetic Fe-based amorphous alloys. The underlying physical origin of these correlations is discussed. Based on these correlations, the influences of various alloying elements are classified. These results are helpful for designing new soft magnetic amorphous alloys with high thermal stability.
