Seminar Abstract

Droplet impact onto a surface is an everyday event that is seen in many industrial applications such as ink jet printing, application of pesticides, cooling of electronics, and every day life events such as rain falling on clothing and erosion of soil due to rain. Classical drop impact onto a solid homogeneous surface has been studied for many decades. However, this talk will provide an overview of more recent studies done by us where there are complexities in droplet (e.g. inclusion of particles), or surface (e.g. softness, porosity, presence of contaminations). Starting with the basics of the droplet impact onto a surface, the attention will be turned to a few special cases where a droplet impacts at the edge of a surface, when a substrate is soft, when a drop impacts a fabric (a soft and porous substrate), when a droplet impacts a heterogeneous surface, and when droplet contains particles.

Speaker’s Biography​

Alidad Amirfazli is a Professor at the York University in Toronto, Canada where he founded the Department of Mechanical Engineering in 2013. He formerly held the Canada Research Chair in Surface Engineering at the University of Alberta, Canada. Amirfazli has produced exciting results in wetting behavior of surfaces, drop adhesion, impact, and shedding from surfaces,  as well as understanding and application of superhydrophobic coatings. He has more than 250 scientific contributions, many in prestigious peer reviewed journals; he has also given many invited talks at international level. He is the Editor for the Advances in Colloid and Interface Science, and an Editorial board member for other journals. Dr. Amirfazli has been the recipient of the Martha Cook Piper Research prize, Petro-Canada Young Innovator Award, and Killam Annual Professorship. In 2014 he was inducted into the Royal Society of Canada’s College of New Scholars, Artists and Scientists.  He also served in the board of Professional Engineers of Alberta, and been a consultant with various companies in USA, Europe, and Canada.
