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.
