| Abstract: | High|speed photography and laser PIV (particle image velocimetry) technology were applied in the study of the jet flow on top of sub|cooled boiling bubbles. In the experiments, heated ultra|thin platinum wires were used to generate vapor bubbles. Based on the velocity field measured, the relationship between the jet flow and the development of the bubbles were discussed. |
