...C. C. Gutiérrez-Torres; Y. A. Hassan; J. A. Jimenez-Bernal Turbulent boundary layer modification in a channel flow using injection of microbubbles as a means to achieve drag reduction was studied. The physical mechanism of this phenomenon is not yet fully understood. To obtain some information...

...Javier Ortiz-Villafuerte; Yassin A Hassan Particle tracking velocimetry has been used to measure the velocity fields of both continuous phase and dispersed microbubble phase, in a turbulent boundary layer, of a channel flow. Hydrogen and oxygen microbubbles were generated by electrolysis...
