Prof. Jose Manuel Gordillo, Pressure-gradient induced generation of microbubbles and of simple and compound emulsions

Date: Wed 8 Apr 2015, 16:00 - 17:00

Location: Nanoforce Seminar Room, Joseph Priestley Building

The Centre for Simulation and Applied Mechanics of SEMS is hosting Prof. Gordillo, a world-expert in fundamental studies on microfluidic generation of drops and bubbles, with applications to industry and medicine. Prof. Gordillo will give a presentation about his research in the Nanoforce Seminar Room (Jason Priestley Building) at 4pm. Your attendance can make the difference!

Speaker: Prof. Jose Manuel Gordillo, Department of Aerospace Engineering, University of Seville (Spain)

Title: Pressure-gradient induced generation of microbubbles and of simple and compound emulsions

When and where: Wed Apr 8, 4pm, Nanoforce Seminar Room, Joseph Priestley Building

Abstract: In this presentation we will show an experimental and theoretical study regarding the generation of monodisperse microbubbles and simple and double emulsions by means of a type of devices such that their geometry not only impose an outer coflow to an inner thin jet of a different fluid, but also a large favourable pressure gradient. It is the main purpose of the talk to highlight the critical role played by the outer pressure gradient in stabilizing the formation of microbubbles and simple and compound microdrops. We will show that the comparisons of slender-body theories with experiments in both the high and low Reynolds limits are in excellent agreement with observations
