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.
We congratulate our PhD candidates Marijn Blommaert and Rose Sharifian to publish two further articles: Intrinsic bipolar membrane characteristics dominate the effects of flow orientation and external pH-profile on the membrane voltage & Bipolar Membrane and Interface Materials for Electrochemical Energy Systems.
Aron Kahn joined the group as a research engineer. After recently completing his master thesis with the title "Hemodynamics in a patient-specific carotid artery: a tomo-PIV, 3D-PTV, and CFD comparison study" in our group, he will apply his know-how in imaging and computational work to develop fluorescence lifetime imaging techniques in our group.
PhD candiates Marijn Blommaert and Rose Sharifian published an article: Orientation of a biploar membrane determines the dominant ion and carbonic species transport in membrane electrode assemblies for CO2 reduction.
Minu Pious joined the group as a research engineer. With her experience as process engineer, she is going to work on designing a process for hydrogen bromine redox flow batteries.
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.
