The methodology disclosed permits the testing of fluids, solids, powders and pastes through the measurements of effusivity. Effusivity is a measurement that combines thermal conductivity, density, and heat capacity. Blend uniformity, homogeneity, miscibility, concentration, voiding/delamination, and moisture content are exemplary of the applications to which the present methodology is applicable. The method of monitoring homogeneity, miscibility, concentration, voiding/delamination, and moisture content in a material comprises the steps of measuring effusivity of a first portion of the material, measuring effusivity of a second portion of the material, comparing each measurement. The comparison may be between the measurements themselves or to a predetermined range of values and indicating which portion has an out of range measurement. The method of monitoring blend uniformity in a mixture containing a plurality of components to be mixed, comprises the steps of providing a first composition and a second composition, each having a different effusivity, mixing said first composition and said second composition, measuring effusivity in said mixture during mixing, determining the relative standard between measurements, and correlating the relative deviation for a determination of blend uniformity. |
