Abstract:

The process of atomization describes the disintegration of a fluid body into a spray of small droplets. From rain and breaking waves to the manufacturing of pharmaceuticals and the coating of surfaces, atomization is pervasive throughout nature and industry. In all cases, the size of the produced droplets is of critical importance to the efficiency of the spray process; however, atomization produces a spectrum of droplet sizes, often leading to wasted product. The physics of atomization are among the most challenging to study due to the need to capture dynamics across several orders of magnitude in scale, from films with thicknesses on the order of nanometers to the entrainment and interaction of droplets over distances of meters. As a result, the established theories of atomization, and thus the established models used to predict the droplet size, have not been sufficiently developed to provide either tools or insight into spray dynamics that allow for the optimization of industrial spray processes, especially when viscous and non-Newtonian fluid properties are important. In this talk, I will present my recent contributions to this research area in developing new theories and modelling approaches, as well as my future work on the effects of particles and emulsion droplets on the atomization mechanisms.

Short bio:

Dr. Isaac Jackiw is an assistant professor in the department of Chemical and Materials Engineering at the University of Alberta in Edmonton, Alberta. He earned his Ph.D. degree from the University of Toronto in 2023, following his B.Eng. and M.A.Sc. degrees from McMaster University, earned in 2016 and 2018, respectively. Prior to joining the University of Alberta, Isaac was a postdoctoral associate at the Massachusetts Institute of Technology, where he held a Natural Sciences and Engineering Research Council of Canada Postdoctoral Fellowship. The focus of Isaac’s research is the atomization of complex fluids (i.e., “sprays with stuff in them”) using both experimental and theoretical approaches to understand the mechanisms that lead to the formation of various droplet sizes in industrial sprays. The goal of this research is to develop methods to control and tailor atomization processes to improve efficiency and reduce waste toward improved sustainability.
