A theoretical analysis is presented for growth of a single, large elliptical finger in a porous medium. The objective is to obtain an understanding of how large fingers develop once a displacement front has become unstable. The results provide information beyond that available from linear analysis, which has been used in most previous work and applies only to infinitesimal perturbations. Separate analyses are given for finger growth during instability of the front accompanying displacement of one immiscible fluid by another, the combustion front in a dry, forward combustion process, a condensation front, and the combustion front in dry, reverse combustion as employed in the linking step of underground coal gasification.
