...Shaobai Li; Youguang Ma; Shaokun Jiang; Taotao Fu; Chunying Zhu; Huai Z. Li The dynamical characteristic of a single bubble rising in non-Newtonian fluid was investigated experimentally. The bubble aspect ratio and rising velocity were measured by high speed camera. The shape regimes for bubbles...

...Fan Wenyuan; Ma Youguang; Jiang Shaokun; Yang Ke; Li Huaizhi The velocity, shape, and trajectory of the rising bubble in polyacrylamide (PAM) and carboxymethylcellulose (CMC) aqueous solutions were experimentally investigated using a set of homemade velocimeters and a video camera. The effects...

...Bu-Geun Paik; Kyung-Youl Kim; Jong-Woo Ahn The objective of the present study is to investigate propeller wake using particle image velocimetry (PIV) technique with bubble type of tracers, naturally generated by the decrease in the static pressure in a cavitation tunnel. The bubble can be grown...

...Haosheng Chen; Jiang Li; Darong Chen To study the drag reduction effect of a bubbly fluid, a pin-disk experiment is performed on the Universal Micro Tribotester system. Bubbles are generated by water electrolysis in holes that are specially designed on the disk surface. Experiment result shows...
