Latest Patents
Samuel Marre holds a significant patent titled "Determination of interfacial tensions in supercritical conditions." This invention details a method that involves:
1. Flowing an inner liquid phase within an inner flow member and an outer liquid phase in an outer flow member, with the inner flow opening within the outer flow. The temperature and pressure in the contact area between the two phases are manipulated to achieve a supercritical state.
2. Varying the flow rate of the inner and/or outer phase to modify the flow profile, during which a torque is identified from the flow rates, known as transition flow rates, marking a change in the flow profile (from drops to a jet or vice versa).
3. Calculating the interfacial tension between the two liquid phases based on the transition torque identified from the modified flow profile.
