| Abstract: | The solidificaton of revolutionary investment castings involving fluid flow due 1o solidification shrinkage is studied by computer numerical simulation. The movements of solidification interface and emptyelemcnt interface, as well as flowfield in solidification, are discussed. The distribution of porosity in investment castings arc computed by direct simulation method. |
