Dendritic Growth with Fluid Flow in Pure Materials
نویسندگان
چکیده
We study the growth of single dendrites from a small initial seed in an undercooled melt in the presence of a forced flow. Three-dimensional models are constructed, in which the solidification is computed using an adaptive finite element mesh and a phase-field method. We compare our calculations with available theories and experiments, and conclude that there are significant open questions remaining about the evolution of microstructure when flow is present.

Convection Effects in Three-dimensional Dendritic Growth
A phase-field model is developed to simulate free dendritic growth coupled with fluid flow for a pure material in three dimensions. The preliminary results presented here illustrate the strong influence of convection on the three-dimensional (3D) dendrite growth morphology. The detailed knowledge of the flow and temperature fields in the melt around the dendrite from the simulations allows for ...
متن کاملThree-dimensional phase-field simulations of the effect of convection on free dendritic growth
Three-dimensional free dendritic growth of a pure material into an undercooled melt in the presence of fluid flow is investigated numerically using the phase-field method. Such computations are made possible by solving the Navier–Stokes equations for the flow and the energy equation for the heat transport on a grid that is twice as coarse as the grid for the phase-field equation. The effect of ...

Based on our previous developed 2D CA-FVM model, where the transport phenomna and kinetics conditions of solute-driven dendritic growth occurred in the solidification process with fluid flow were totally taken into consideration, an extensive model validation and furhter model application are demonstrated here. Firstly, the flow pattern of the lid-driven cavity is well predicted and quantitativ...

Dendritic solidification of pure materials from an undercooled melt is studied using the extended finite element method/level set method for modelling the thermal problem and a volume-averaged stabilized finite element formulation for modelling fluid flow.

متن کاملA level set simulation of dendritic solidification with combined features of front-tracking and fixed-domain methods
A method combining features of front-tracking methods and fixed-domain methods is presented to model dendritic solidification of pure materials. To explicitly track the interface growth and shape of the solidifying crystals, a fronttracking approach based on the level set method is implemented. To easily model the heat and momentum transport, a fixed-domain method is implemented assuming a diff...
