Abstract The collision process between a Newtonian liquid jet and pro/hydrophobic surfaces was investigated in this paper. Based on the theory of impinging-jets, a theoretical model of liquid sheet was established which comprehensively considered the effects of pro/hydrophobicity on surface tension force and the energy loss during the entire impinging process. The sheet parameters such as the size, velocity and thickness distribution were obtained. In order to validate the theoretical model, a corresponding experimental set-up has been developed, using deionized water as experimental working medium and 3 different pro/hydrophobic surfaces as experimental parts. The comparisons showed the theoretical results are in good agreement with the experimental data. In addition, the influence of surface pro/hydrophobicity on the sheet characteristics was theoretically discussed, and the results showed the surface pro/hydrophobicity could significantly affect the size of liquid sheet on solid surface.
