Computational and laboratory investigations of a model of blood droplet flight for forensic applications

We present a three-dimensional, forward model of blood droplets in ight. The proposed model is based on a set of ordinary di erential equations (ODEs) incorporating viscous drag and gravitational forces. We validate the model against laboratory experiments in which a mock crime scene is constructed...
