Computational Analysis of Nonuniform Expansion in Polyurethane Foams

Computational Analysis of Nonuniform Expansion in Polyurethane Foams

This paper computationally investigates heterogeneity in the distribution of foam fraction in chemically expanding blown polyurethane foam. The experimentally observed disparity in the volumes of expanded foam when an equal mass of the foaming mixture was injected into tubes of different dimensions...
