Abstract

According to the characteristics of Low Pressure Casting （LPC）

fluid flow calculations ignoring heat transfer are simplified excessively and hence not correct. In order to simulate the mold filling stage of LPC properly

both fluid flow and heat transfer must be taken into account. Therefore

a 3 D numerical simulation program coupling fluid field and temperature field of LPC has been developed. The practical applications show that the software can be used to analyze the mold filling process of LPC properly.
