Evaluation of the performances of hydrophobic woven meshes versus liquids having different surface tension in the fuel-water separation applications

In this study a new methodology has been defined for a deep understanding of the wettability of several woven meshes against liquids having very different wetting behaviour, such as water and jet fuels. At first, we refined the conventional Wilhelmy dynamic contact angle (DCA) technique using several reference solutions having surface tension values between 20-70mN/m. In this way we covered the range of all the liquids involved in the real world applications. Successively, the study of the woven meshes was completed by the measure of the liquid intrusion pressure (LIP) with the same reference solutions used for DCA measurements. Correlations between DCA and LIP were finally discussed. Copyright © Taylor & Francis Group, LLC.
