Announcement of CNIE Inspiration Grant: Pulsating flow inspired by blood circulation to improve fluid dynamics in flow reactors and crystallizers

08 January 2016

We are pleased to announce that Prof Asterios Gavriilidis (in collaboration with Dr Luca Mazzei (UCL) and Prof Chris Price (University of Strathclyde)) has been awarded a Centre for Nature Inspired Engineering Inspiration Grant to perform a collaboratory project – Pulsating flow inspired by blood circulation to improve fluid dynamics in flow reactors and crystallizers between the CNIE at UCL and University of Strathclyde.

In this research project, he aims to initiate a study that will enable the development of a nature-inspired microfluidic system that is able to improve the residence time distribution (RTD) and aid in addressing channel fouling by applying pulsation in channels, taking inspiration from blood circulation systems. The human cardiovascular system is a good example in which pulsating flow is found. The pulsating blood flow in the circulatory system is produced by the pumping action of the heart. The blood is conducted into the arteries, across the micro-circulation and finally back, via the venous system, to the heart. For instance, almost parabolic Poiseuille profiles, and therefore low Womersley numbers, are observed in venules, arterioles and capillaries, whilst aorta arteries and vena cava blood vessels are dominated by flat velocity profiles and large Womersley numbers. An experimental platform will be developed to quantify the effect of pulsating flow on the narrowing of RTDs.
