Experimental validation of a numerical model for predicting the trajectory of blood drops in typical crime scene conditions, including droplet deformation and breakup, with a study of the effect of indoor air currents and wind on typical spatter drop trajectories

Highlights • Bloodstain pattern analysis provides valuable information about violent assaults. • We developed a numerical model of blood drop flight, incl. drop deformation and breakup. • Predictions agreed with experimental data within 5%. • It can be used to answer such questions as how wind affec...
