The evolution of jet surface structure plays a key role in various atomization related applications. In this paper, the jet surface structures of two different nozzle configurations are captured and measured based on high-speed microscopic photography and a novel image processing method. Results show that the primary wavelength of surface wave decreases exponentially with Weber number and increases linearly with streamwise distance for both two nozzles. The primary wavelength that non-dimensionalized with boundary layer thickness is almost a constant for the same nozzle, but obviously different for different nozzles. The nozzle configuration has a significant effect on the scale of the surface structure when the Weber number is smaller than 50, however, this effect is limited for bigger Weber number.
