Department of Chemical and Process Engineering at ChemEngDay and UK Particle Technology Forum

Surrey certainly looked like one of the more active UK departments!

On 27-29 March 2017, over 20 academics and researchers from the Department of Chemical and Process Engineering at the University of Surrey attended the IChemE ChemEngDay 2017 and the UK Particle Technology Forum 2017, both held at the University of Birmingham. At these conferences, they presented a wide range of research topics, including; product engineering, energy generation, storage and utilisation, catalysis and sustainable green chemistry, biological engineering, chemical engineering at interface, and particle technology, showcasing the diverse research activities in the department.

We would like to congratulate all researchers for their research achievement, in particular, the following prize winners:

Maggie Svensson, Prize Winner in the theme of Water Process Engineering/Water Management, with the poster entitled "The effect of novel binders on the performance of captive deionisation for water purification."

Jianyi Zhang, Prize Winner in the theme of Product Engineering, with the poster entitled "The effect of water content on mechanical properties of microcrystalline cellulose and Mannitol powders."

Paschalia Mavrou, 3rd prize for the best young researcher award, with an oral presentation entitled "Predicting Moisture Migration in Composite Food Systems during Storage."

Alexandros Stavrou, 1st poster prize winner, with the poster entitled "Flowability Assessment of Weakly Consolidated powders." Alex’s poster describes his measurements of powder flowability at stresses below 1 kPa using a shear cell and the developing technique of ball indentation. The shear cell measures the unconfined yield stress, whereas ball indentation measures bed hardness, which is equal to the unconfined yield stress multiplied by a constraint factor. The constraint factor is expected to depend on particle properties.

Alex has demonstrated that both particle size and particle size distribution have no effect on the constraint factor, and that the ball indentation and shear cell methods show good agreement, though the shear cell method cannot be applied for all powders in this low stress range. Alex has just entered the third year of his project funded by the International Fine Particle Research Institute, and his future work will explore how other particle properties (such as shape and surface energy) influence the constraint factor.

After the event Professor Jonathan Seville commented: "Having been at ChemEngDayUK and the PTF meeting myself as President of IChemE, I would like to congratulate all those who participated from Surrey. It was a very good turn-out and there were some excellent posters and presentations. Surrey certainly looked like one of the more active UK departments!"
