Porosity formation in axi-symmetric castings produced by counter-pressure casting method

摘要

We propose a method for simultaneous treatment of heat and mass transfer processes and porosity formation of castings produced by Counter Pressure Casting (CPC) method. The method enables us to account for the influence of the CPC parameters on the mechanical properties of the casting. Numerical results and comparison with experimental data are given for an axis-symmetric casting (hemisphere with constant wall thickness).
