The paper describes the experimental setup for the investigation of the unsteady cavitating flow around a prismatic NACA 2412 hydrofoil with cavitation instabilities and the results of the CFD analysis.
Prediction of surface tension of binary mixtures with the parachor method
Němec, Tomáš
The parachor method for the estimation of the surface tension of binary mixtures is modified by considering temperature-dependent values of the parachor parameters. The temperature dependence is calcu- lated by a least-squares fit of pure-solvent surface tension data to the binary parachor equation utilizing the Peng-Robinson equation of state for the calculation of equilibrium densities. A very good agreement between experimental binary surface tension data and the predictions of the modified parachor method are found for the case of the mixtures of carbon dioxide and butane, benzene, and cyclohexane, respectively. The surface tension is also predicted for three refrigerant mixtures, i.e. propane, isobutane, and chlorodifluoromethane, with carbon dioxide.
