Chemical Engineering at the School of Engineering

As part of the University of Edinburgh's 'You Said, We Listened' campaign, the School has designed a series of posters, demonstrating how we use the comments of our students to improve their University experience.

Bubbling fluidization has been widely applied in process industries, such as power generation from coal, renewable energy production, gasification and pyrolysis. In this study, we attempted to predict solid flow patterns, solid and gas mixing, bubble behaviour in a bubbling fluidized bed based on operational conditions and bed design.

Pore wetting is a principal control of the multiphase flows through porous media. However, the contact angle measurement on other than flat surfaces still remains a challenge. In order to indicate the wetting in a small pore, we developed a new pore contact angle measurement technique to directly measure the contact angles of fluids and gas/liquid/supercritical CO2 in micron-sized pores under ambient and reservoir conditions in this study, as well as the effect of chemical functional groups on pore contact angle.
