Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Simulation of non-Newtonian droplet splatter using Smoothed Particle Hydrodynamics

Abstract: Droplet splatter dynamics is an important study in the field of forensics since a crime event can produce many blood stains. Understanding the origins of the blood stains from pure observations is very difficult because much of the information about the impact is lost. A theoretical model is therefore needed to better understand the dynamics of droplet impact and splatter.\r\n\r\nSmoothed particle hydrodynamics (SPH) is a simulation technique that has originally been developed to study astrophysical phenomena. It has since been developed to simulate a wide variety of fluid systems and been applied to many areas such as solid mechanics, fluid dynamics, high-velocity impacts, as well as other non-scientific areas such as CGI and video game development.\r\n\r\nThe development of the mathematical model for simulating non-Newtonian droplets with SPH is presented along with some of the challenges that are faced when using this specific simulation technique.
