Transport Phenomena

The Transport Phenomena group studies the transport of mass, momentum and heat in physical and (electro)chemical processes related to advanced materials processing, energy conversion and storage, and health. Our main interest is in transport around (solid-fluid, liquid-gas, liquid-liquid, membrane-fluid and electrically charged) interfaces, which we wish to understand, control and enhance.

We enjoy performing fundamental research to gain a deep understanding of the underlying phenomena, while at the same time we find it important to apply our knowledge to real-life applications.We use both theoretical and computational models, and non-intrusive experiments based on laser and X-ray techniques.

November 2020:
The construction of the TOMOCON inline swirl separator has been completed. This inline separator uses centripetal acceleration to separate fluid phases based on their density difference. Because the emerging accelerations are several times larger than gravity, this separation process has a much smaller footprint than conventional liquid-liquid separators. However, the benefit of the more compact device comes with a cost of a highly dynamic system, in which the efficiency of the separation is deeply connected to changes in the concentration of the mixture reaching the separator. One of the targets of TOMOCON is to verify whether or not state of the art techniques as electrical resistance tomography and wire-mesh sensors can be used to control the separation in real time.

TOMOCON inline fluid separation team with supervisor Dr. Luis Portela.

Yanyan Liu joined the group as a Postdoc. With her experience in mass transfer in multi-phase flow and microfluidics, she is going to work on the scale-up of reactions in Pickering suspensions. 

October 2020:
Dr. Bijoy Bera joined the group as assistant professor. He is an expert in interfacial phenomena and (co-)author of 15 ISI journal papers.
