Numerical Study on Solidification Process and Shrinkage Porosity for Engine Block Casting
The latent heat releasing and the criterion for shrinkage porosity in solidification progress of casting are studied. A numerical analysis is presented for solidification progress of the cylinder head casting using finite element method. The temperature distributions of the casting in different solidification phases are solved, and the shrinkage porosity is predicted. Based on this, the solidification progress of casting is evaluated. The simulation results can offer a helpful reference for casting design of cylinder head casting.
