Kurzfassung
A free dendrite growth during solidification into external forced flow is analyzed using a sharp interface model. A criterion for selection of the stable growth mode is derived for the axisymmetric dendrite growing into non-isothermal binary system under convective flow. The criterion obtained rallies analytic results for dendrite growth under forced convection in a pure system [Ph. Bouissou, P. Pelce, Phys. Rev. A 40 (1989) 6673] and dendrite growth in a stagnant binary system [M. Ben Amar, P. Pelce, Phys. Rev. A 39 (1989) 4263].

| Zusätzliche Informationen: | Reviewer Report: The authors provide an analysis of dendritic growth in the presence of forced convection. The main new feature is that the analysis of Ph. Bouissou and P.Pelce is extended to the case of a binary alloy, where heat and solute diffusion play both a role. I find this paper extremely useful, because exactly this case was missing in the literature so far - the authors should be thanked for undertaking the tedious derivations. All results appear to be correct. The paper is also well written. I recommend that the paper be published as is. | ||||||||||||||||
