Using the Direct Light Processing method, minichannel mixers with different liquid and gas junction angles (from 30° to 150°) relative to the minichannel axis were manufactured. An experimental study of the two-phase flow formation was carried out, where Milli-Q® water was used as a working liquid, and high purity nitrogen was used as a working gas. A method of two-phase flow characteristic analysis using a high-speed shadow technique and automatic postprocessing was developed. Two-phase flow regimes were investigated in a wide range of gas and liquid flow rates. Size distribution of gas bubbles and liquid slugs and the distribution of bubble velocities were analyzed.
