Simulation of the Stir Casting Process
Non homogeneous particle distribution is one of the greatest problems in casting Metal Matrix Composites (MMC's). To optimize some of the parameters for uniform particle distribution for batch compocasting the present simulation studies were conducted. The simulation involves visualisation experiments. In the visualisation experiments liquid and semi solid aluminium are replaced by other fluids...
متن کاملNumerical Simulation of the Investment Casting Process
Determining alloy shrinkage factors is very important for the investment casting process. Casting dimensions can be obtained from numerical simulations of heat transfer and deformation phenomena. The accuracy of the dimensional results depends on heat transfer results. In order to validate heat transfer models, temperature data were obtained during casting of aluminum alloy A356 in shell molds ...
متن کاملThermal Simulation of Solidification Process in Continuous Casting
In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
متن کاملComparative Analysis Of Aluminium Metal Matrix Composites Reinforced With TiC And TiB2 Using Stir Casting Process
Composite materials are playing major and vital role in various sectors especially in aeronautical, defence and automotive sectors. It is preferable because of obtaining unique characteristics such as high specific strength, high stiffness, high corrosion resistance and low density. In the present work deals with the influence of Titanium carbide and Titanium boride reinforcements in different ...
متن کاملFlow simulation of gallium in a cylindrical annulus in the presence of a magnetic field for improving the casting process
Free convection flow in an enclosure filled with a congealing melt leads to the product with a nonuniform structure involving large grains. The convective flows are decreased by applying an appropriate magnetic field, obtaining uniform and small grain structures. In this work, using the finite volume method, we investigated the application of a magnetic field to the convective heat transfer and...
