Bullet Shape, Velocity Determine Blood Spatter Patterns
American Institute of Physics (AIP)Blood spatters are hydrodynamic signatures of violent crimes, often revealing when an event occurred and where the perpetrator and victim were located. Researchers have worked toward gaining a better physical understanding of the fluid dynamical phenomena during gunshot spatters, which could enhance investigations. In the Physics of Fluids, they propose a generalized model for the chaotic disintegration of a liquid due to an arbitrarily shaped projectile. Their model focuses on providing predictive models of gunshot blood atomization and droplet flight and spattering.
