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. We chose to explore a fluid modelling method
known as Smoothed Particle Hydrodynamics (SPH) to determine whether it is capable
of modelling droplet splatter accurately. Specifically, we chose to investigate an SPH
version of a non-Newtonian pressure correction method with surface tension. Three
experiments were performed to analyze the different aspects of SPH. From the results
of the experiments, we concluded that this method can produce stable simulations if
an artificial viscosity model is included, a third-order polynomial kernel is used and
the pressure boundary condition on surface particles are non-zero. / UOIT
