Dendritic solidification along liquid-liquid interfaces — •Claas Hüter1,2, Guillaume Boussinot1,2, Efim Brener2, Dimitri Temkin2, and Robert Spatschek2 — 1MPIE, Düsseldorf — 2Forschungszentrum Jülich
Solidification of an asymmetric dendrite along the interface of two liquids is discussed. The considered system shows a monotectic reaction, the diffusion equations and the associated thermodynamic boundary conditions are represented by three coupled nonlinear integral equations. The selection in this case determines the velocity, the lengthscale of the parabolic asymptotics of the dendrite and the lengthscale which defines the liquid-liquid interface. These quantities are determined as functions of the undercooling numerically.
