dc.description.abstractPolyurethane foams were produced by using a homogenizer as a mixing equipment. Effects of stirring speed on the
foam structure were investigated with SEM observations. Variation of the bubble size, density of the foam, compressive
strength, and thermal conductivity were studied. A hybrid foam consisting of polyurethane foam and commercial polystyrene
foam is produced. Mechanical and thermal properties of the hybrid foam were compared with those of pure polyurethane
foam. Advancement of flow front during mold filling was observed by using a digital camcorder. Four types of mold geometry
were used for mold filling experiments. Flow during mold filling was analyzed by using a two-dimensional control volume
finite element method. Variation of foam density with respect to time was experimentally measured. Creeping flow,
uniform density, uniform conversion, and uniform temperature were assumed for the numerical simulation. It was assumed
for the numerical analysis that the cavity has thin planar geometry and the viscosity is constant. The theoretical predictions
were compared with the experimental results and showed good agreement.
