Ross-Miles pour test

Figure 2.11. Schematic of the apparatus used in the Ross-Miles pour test. (ASTM (American Society for Testing and Materials) D1173-63 Standard test method). The foam volume is measured immediately after the generation of the foam, and again after periods of 5 and 10 min...

It is well known that impact of inherent liquid drops can also cause air entrainment (see, e.g., reference [50]), a process that is in fact the basis of the well-known Ross-Miles pour test [51] (see Section 2.2.3). That drop impact can cause both the formation and destruction of foam would seem to be contradictory. It is, however, clearly a real effect that probably concerns the relative magnitude of variables such as the gas phase volume fraction in the foam, foam film thickness, and drop properties such as size, velocity, and frequency. Such a vague statement suggests the need for improved understanding of the phenomena associated with inherent liquid drop impact on foam and foam films.
