摘要:
Methods and related systems are described for determining a property of a solid material relating to wettability, and for evaluating chemical additives. A solid particle is positioned at an interface between a lighter fluid phase, such as oil, and a denser fluid phase, such as water. An external force is applied, preferably with a centrifuge, so as to urge the solid particle into the denser fluid phase. An observation is made as to whether the particles has passed through the denser fluid phase, and based on the observation the contact angle is calculated. The calculation is also based on the densities of each fluid phase, of the solid material, the amount of the external force applied, size of the solid material, and interfacial tension between the two phases. The calculation also preferably accounts for two curvatures representing the interface between the first phase and the second phase as deformed by the solid material.
