Simulation Study on the Factors Affecting the Solidification of Liquid Droplets with Different Salinity on Cold Surfaces

Salt spray splashing on the structural surfaces of ships is a common difficulty in polar navigation. In this paper, experiments are designed to study variation growth peak pure water droplets surface hydrophobic coating with contact angle 90°, and numerical simulation method verified according experiment. The calculated by consistent experiment, calculation error freezing time obtained less than 10% that processes salinity levels 0, 10, 20, 30, 40, 10 μL hydrophilic, hydrophobic, super plates studied. calculated, along effects wall temperature, angle, process droplets. results show increased dramatically increasing salinity. influence substrate temperature was also concentrated. All these contribute better understanding icing mechanism marine surfaces.
