We study the effect of fluid flow on three-dimensional (3D) dendrite growth using a phase-
field model on an adaptive finite-element grid. In order to simulate 3D fluid flow, we use an …

A numerical study of the effect of an external mean flow on dendritic growth has been
performed. All simulations are 2D phase-field computations using an adaptive finite element …

Previous studies on directionally solidified hexagonal close-packed (hcp) sea ice have
found that the c-axis orient parallel to a shear fluid flow that is driven external to the solute …

It is recognized that flow in the melt can have a profound influence on the dynamics of a
solidifying interface and hence on the quality of the solidified material. To better understand …

Fluid motions impressed upon a eutectic crystal front during directional solidification result in
an increase of the lamellar spacing. This flow-induced change of microstructures is analyzed …

A controlled flow experiment was developed to evaluate solidification phenomena in
aluminum-0.1, 2.5, and 4.5 wt.% copper alloys. The apparatus was designed to investigate …

Metal and semiconductor manufacturing represents an important and highly contested
fraction of the United States economy. The typical production route for these materials …

A multi-phase field model was used to study the three-dimensional dynamics of morphology
evolution in binary eutectics. Performing the calculations in three dimensions enables the …

A linear stability analysis as well as nonlinear simulations are performed in order to analyse
the coupling between the directional solidification of a binary alloy and the flow in its melt …

Morphological instability is discussed via linear and nonlinear theories. Couplings with
forced flows and convecting melts are discussed in terms of physical mechanisms and …
