High-pressure drop shape analysis system
The high-pressure drop shape analysis system (HP-DSA) enables the evaluation of interfacial properties such as interfacial tension, wetting and volumetric expansion at elevated pressures and temperatures up to 70 MPa and 200 °C, respectively. The system operates based on the Axisymmetric drop shape analysis technique. Using a high-resolution camera, the software detects the contour of the actual drop to which a theoretical drop profile is fitted. A set of differential equations are numerically solved by a profile optimization algorithm, and a relation between the radius of curvature, the bond number and the IFT is obtained. Similar steps are followed for the determination of the contact angle (wetting). The HP-DSA has wide applications in the oil and gas industry and material characterization.
