| Abstract: | A small-scale refrigeration system and an image acquisition system was desigued and built. Under the different working conditions, lots of two-phase flow images at different positions of the capillary tube were obtained. Based on the digital image manipulation theory, exploit a method to manipulate the twophase flow images. Two-phase flow characteristics of refrigerant in capillary tube with the manipulated images was analyzed. |

| Keywords: | adiabatic capillary tube two-phase flow visualization image manipulation |
