The aim of the present work is to explore through the developed numerical model the separation of exosomes from a more complex mixture of particles i.e. red blood cells and white blood cells, through combined acoustofluidics and fluid relocation in a bulk acoustic wave microfluidic ... Read More

Multiphysics Simulation and Validation of Field Aging of Asphalt Pavements

E. Omairey[1], Y. Zhang[1]
[1]Aston University, United Kingdom

Field aging of asphalt pavement plays a vital role in limiting the pavements’ service life, and it is one of the major reasons for road maintenance. A long-term field aging results from the oxidation of asphalt mixtures when exposed to the ambient environmental conditions for extended ... Read More

Simulating the Effect of a Change in Deposit Geometry on the Performance of a Soluble Lead Flow Cell

E. Fraser[1], R. Wills[1], R. Kahanda Koralage[1]
[1]University of Southampton, United Kingdom

Introduction The soluble lead flow battery (SLFB) is a form of redox flow battery (RFB), an electrochemical device where energy is stored in a liquid electrolyte. The electrolyte is pumped around a flow circuit from a reservoir to the cell where redox reactions occur and the energy is ... Read More
