Evaporation of Bio-droplets

Abstract:

During the evaporation of a droplet of biological fluid on a substrate (serum blood, urine), complex patterns are observed. Any alterations in the components of biological fluids, caused by diseases, lead to different drying drop patterns. This work aims to gain an understanding on the mechanisms implicated in the evaporation of bio-droplets including salt crystallisation and protein precipitation, the interactions between proteins and electrolytes, as well as the effect of the environmental conditions on the final pattern formation.

Bio:

Marina Efstratiou is currently a PhD student at the University of Edinburgh in the Institute of Multiscale Thermofluids. She obtained her bachelor's degree in Mechanical Engineering and her MSc degree in Biomedical Engineering from the Cyprus University of Technology. Her research explores the evaporation of droplets from biological fluids for the investigation of the final patterns that arise after the complete desiccation of the droplets.

Laser diagnostics for surface and fluid thermometry in transient heat applications

Abstract:

Laser diagnostics promote our understanding of heat transfer phenomena to and from solid surfaces, and in fluids. Here, two of such optical techniques will be presented; phosphor thermometry and Coherent anti-Stokes Raman Scattering. This talk also presents the combined implementation of these techniques in a fixed-volume chamber to study highly transient heat transfer processes relevant to an IC engine operation. This implementation offers insight to the influence of flame-induced gas thermal variations on unburned gases ahead of the propagating flame, and on heat losses to walls.

Bio:

Anthony is a research associate at the University of Edinburgh’s Institute for Multiscale Thermofluids. He obtained his PhD in Mechanical Engineering from Imperial College London. His current research focuses on the application of laser diagnostics to study thermal heat loss to walls and their effect on near-wall gas distributions in a fixed-volume chamber under transient pressure conditions.
