These images show liquid carbon dioxide jets emerging a nozzle into stagnant air at atmospheric pressure. The jet’s velocity is about 100 m/s, the diameter is 0.17 mm. Because carbon dioxide can only exist as a gas or a solid at atmospheric pressure, the liquid CO2 jet can only exist for a short time, thus gas bubbles are formed within the jet downstream the nozzle. This process is depicted in various magnification stages. The images were taken with a high speed camera.
