    摘要: The invention concerns a method whereby: (E1) an inner liquid phase is made to flow in an inner flow member, and an outer liquid phase in an outer flow member, the flow of the inner liquid phase opening within the flow of the second liquid phase; and the temperature and pressure in the contact area between the first and second liquid phases being such that the first and/or second liquid phase is in the supercritical state, (E2) the flow rate of the inner phase and/or outer phase is varied in such a way as to modify the flow profile, and a torque is identified from values of the flow rates of the inner and outer phases, called transition flow rates, from which the modification in the flow profile occurs (from drops to a jet; or from a jet to drops); (E3 ) from the transition torque identified in step (E2), the value of the interfacial tension between the two inner and outer liquid phases is calculated, or the result obtained is compared to that obtained for another torque in the conditions of steps (E1) and (E2).

    摘要: The interfacial tension between two liquids is determined by: flowing an internal liquid (Li) through an internal flow member (2) and flowing an external liquid (Le) through an external flow member (4), with conditions being first established such that either droplets (G) of the internal liquid are formed in the external liquid, or a continuous jet of the internal liquid is formed in the external liquid, the continuous jet of the internal liquid then being formed in the external liquid or droplets of the internal liquid then being formed in the external liquid, and deducing therefrom the value of the interfacial tension between these two liquids.

    摘要: A process and device for characterising complex fluids such as emulsions, gels, surfactant solutions and others and appliances resulting therefrom for characterising fluids on the basis of the process used. The process comprises simultaneously managing the device controlling the preparation process and the measuring device. The results of the measurements and the parameters controlling the preparation process are displayed on a common computer screen in real time, thereby enabling to establish a correlation between measurements, observation and control of the process. Two devices are disclosed, a first which is a single-function device for characterising complex fluids being manufactured, and a second, which is a multiple function device for use in laboratory formulation.
