Digitized edition from print [produced by Defence Research and Development Canada]. Includes bibliographical references (page 19). The paper continues the development of physical and mathematical models applicable to liquid drop absorption and evaporation from a substrate. Three examples are considered: a constant radius of curvature model; a constant base area model; and a constant angle of contact model. All allow the free surface area of the drop to vary with time. Methods of solution are given for both monodisperse and polydisperse drop distributions, and the results are compared with experimental data. Both the constant radius of curvature and constant angle of contact versions provide reasonable fits to experiment. Includes abstract in French. Drops Computer simulation.
