上升单气泡与壁面相互作用的图像测量研究

two phase flow experiment emphasized on behavior of rebound after a single bubble and an inclination wall collision through stationary liquids. For the sake, high-speed photography and digital image processing technology was employed. Experimental device is designed, lighting scheme, test procedure and the processing techniques of digital image is presented, parameters about motion trajectory, rising velocity and rebounding velocity after collision of a single bubble with inclination wall were obtained separately for a single bubble in the stationary liquids. initially obtained some regularity of bounding and collision of a single bubble with inclination wall through stationary liquids.
