Abstract
Chrysler's 2.0-liter/four-cylinder gray iron
engine block is modeled using Technalysis' finite element metal casting
analysis program PASSAGE®/PowerCAST. The effect of different gating
designs are investigated to determine the variations in filling patterns and
temperature distributions. The results of the numerical simulations
performed are used for evaluating different design situations.
Introduction
Simulation of metal casting processes using
computer programs which include flow and phase change effects has gained
attention during the recent years. A number of commercial casting analysis
codes are now available for foundry engineer's usage. In spite of many
advancements in this field during recent years, simulation of engine block
remains as one of the most challenging cases due to complexity of its
geometry and the need for accurate prediction of flow and heat transfer. In
this paper we present our recent experiences gained in modeling of an engine
block using the computer program developed at Technalysis.
