Abstract
We summarize the main results and implications of our work on the calculation of cellular shapes in directional solidification using the asymptotic matching method introduced by Dombre and Hakim. For cells with narrow grooves, the finite Péclet number corrections to the cellular profiles that reduce to the Saffman-Taylor solutions for Péclet number p → 0, turn out to be small. We argue that there are several discrepancies between the behavior of these Saffman-Taylor like cells and those observed in experiments as well as numerical studies that suggest that this branch of solutions is not always the physically relevant one for directional solidification.
