... Abstract How microbubbles behave inside turbulent boundary layers are investigated experimentally. Water electrolysis is applied for generation of microbubbles in water, of which electrodes are flash mounted on the solid wall in the upstream section of the measurement area. Four kinds of solid...

... 30 07 2010 Two microfluidic devices for generating microbubbles are considered in the study presented in this paper. The first device consists of a liquid channel and a gas channel that is perpendicular to each other. In this device, the microbubble diameter varies inversely...

... 26 03 2009 Measurements of the velocity fields and wall pressure have been performed in a microbubble laden boundary layer in order to have a better understanding of the degree of correlation between these two parameters. Cross-correlation coefficients have been obtained from...

... Synergy Drag Reduction Polymer Microbubble turbulent boundary layer Drag reduction (DR) experiments with combined micro-bubble and polymer solution injection were conducted in a water tunnel at the ARL/Penn State. Previous research has shown that gas injected upstream of polymer...
