Dendrite growth under forced convection: analysis methods and experimental tests

摘要: An analysis is given of the nonisothermal growth a dendrite crystal under forced fluid flow in binary system. The theoretical model utilized employs free moving crystal?liquid interface and makes use Oseen approximation for equations motion liquid. A criterion stable two-dimensional three-dimensional parabolic dendrites derived assumption an anisotropic surface tension at interface, which generalizes previous known results with convection one-component two-component system rest. obtained within hydrodynamic extended to arbitrary Peclet numbers multicomponent Model predictions are compared experimental data on kinetics droplets processed electromagnetic electrostatic levitation facilities. Theoretical simulation methods currently being developed applied crystallization processes earthly reduced gravity conditions.
