Abstract :In this study, the spreading profiles of the impinging liquid jets on the superhydrophobic/hydrophobic surfaces have been examined experimentally and predicted using experimental data. The liquid jet is sent on the flat and smooth hydrophobic surfaces, which have 93, 104 and 117° contact angles, using the glass tube nozzle with the 1.75 mm inner diameter. The inclination angles between the jet and surface are altered in the range of 15-45°. The predicted profiles compared with the experimental data. The spreading behaviour of the impinging liquid jet on the hydrophobic surface is clarified using the predicted equation. The inclination angle is a dominant parameter for the profile of the spreading liquid. The predicted equation is in a good agreement with the experiments. The front length of the spreading liquid takes the maximum value at a critical inclination angle.Keywords : Liquid jet, hydrophobic surface, spreading profile, impinging jet
