Scaling Analysis of Alloy Solidification and Fluid Flow in a Rectangular Cavity momentum were scaled in order to determine the dependence of various aspects of solidification on the process parameters for a uniform initial temperature and an isothermal boundary condition. This work improved on previous analyses by adding considerations for the cooling bulk fluid flow. The anal

The Fluid Flow and Solidification Phenomenon in Billet Continuous Casting Process with Mold and Finantinuous casting with mold (M-EMS) and final electromagnetic stirrings (F-EMS). The columnar region was regarded as a porous media and a generalized approach was used to calculate permeability, while for the equiaxed zone, a variable apparent viscosity model was applied to simulate the fluid flow at

Columnar-to-Equiaxed Transition in zn-27wt.%al Alloys: A Comparation Between Vertical and Horizontald horizontal arrangement of experimental device. The main parameters analyzed include cooling rate of the melt, position of the solidification fronts for solidus and liquidus temperatures, velocity of solidification fronts and temperature gradients. In both type of solidifications the CET does not o

Microstructure Investigation of Aluminum Die-Cast Parts with Different Gating Conditions Tested in Fd fatigue life and a change in the failure location of the evaluated parts compared with the baseline parts, which prompted submission of both sets of samples for metallurgical evaluation. Optical microscopy, scanning electron microscopy and non-destructive X-Ray imaging tools were employed to chara

A Coupled Thermo-Mechanical Simulation on Squeeze Casting Solidification Process of Three-Dimensionag ANSYS Parametric Design Language (APDL). The effect of volume shrinkage due to cooling and solidification, the effect of pressure on the latent heat release, the mutual dependence of interfacial heat transfer and casting deformation, and materials behavior under elevated temperatures were taken in
