I am a Lecturer in Mechanical Engineering at the Institute for Materials and Processes in Edinburgh University. My expertise is in the modeling and simulation of particle (granular)/particle-laden systems.
Dr Pedro J Sáenz (supervised by Dr Prashant Valluri and Professor Khellil Sefiane) of the Institute for Materials and Processes within the School of Engineering, has won the ARCHER Image Competition The simulation work in the Complex Fluids and Multiphase Flows Group is also supported by the
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.
Enhanced oil/gas recovery and CO2 storage are a displacement process at pore scale, in which oil and gas are displaced by water or CO2 in reservoir at pore scale, or water is displaced by CO2 in aquifers at pore scale. This displacement is controlled by pore structure, pore wettability, pore surface chemistry, fluid viscosity and interfacial interaction between pore fluids and pore surfaces. The displacement controls the pore connectivity, therefore oil/gas recovery and CO2 storage capacity. We investigate the displacement and the effect of various factors on the displacement at pore scale and core scale.
Dr Jiabin Jia obtained his BEng (2002) in Electronics Engineering and MSc (2005) in Electrical and Electronics Engineering at Wuhan University, China. After worked one year in the Hardware R&D department of H3C Technology Co.
My work centres around the development of understanding and mathematical models for complex multiphase flow patterns to tackle various industrial problems like cleaning, oil-gas transport, slurry transport, distillation, absorption, ther
