On Numerical Simulation of Casting in New Foundries: Dynamic Process Simulations

Numerical 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 ...

Thermal 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 ...

Numerical Simulations of Metal onto Composites Casting

The technical community of today is making increasing demands on weight reduction mainly for energy savings, particularly in the automotive industry, but also for better product ergonomics, for instance in the power tools sector. A lightweight product is usually produced using lightweight materials, for instance by integrating composites components into classical metal structures. This approach...

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...
