Abstract
A method for filling a compartment cavity, such as a refrigerative unit cavity, with a foam produced by an expansion and solidification of a foaming mixture of predetermined chemicals. A known amount of the foaming mixture is created in a test chamber cavity and preselected parameters (such as free surface height and pressure) are measured to obtain the average density and apparent viscosity of the foam as a function of time. A computer program uses the average density and apparent viscosity data to simulate the foaming process for various starting quantifies and starting locations of the foaming mixture. A preferred quantity and location are chosen from a particular computer run which satisfies predetermined fill criteria. The preferred quantity of the foaming mixture is then created at the preferred location in the compartment cavity.
