Abstract

A computational flow model has been developed that accounts for the volume expansion and viscosity behavior of thermosetting polyurethane foam with water as the blowing agent in pour molding of polyurethane foam. This model was then used to investigate the effects of (a) varying pour distribution and (b) restricted air flow through vents on the merging of expanding flow fronts and air pocket formation in a vented rectangular mold cavity with a rigid rectangular insert.
