The water crown deformation process of a liquid droplet oblique impacting a curved liquid film was simulated by using the coupled level-set and volume-of-fluid method. The morphological differences of the front and back sides of the water crown were compared. The jet sheet is thin and splash occurs at the front, while the crown sheet is stable and smooth at the back. The influence of impact angle on the shape of water crown is analyzed. Influence of impact angle on rear water crown height is quantified. The rim of the water crown presents an inclined line, and the variation of its inclination angle affected by the impact angle is studied. The position deviations of water crown cavities at different impact angles are investigated. With the decrease in impact angle, the spreading coefficient of the front side of the water crown cavity increases, while that of the back side decreases, and the displacement difference of the front water crown is smaller than that of the back water crown.
