The Splatter Blood For Blood Spatter Analysis - consider
Link to article: Experimental and numerical study of blood backspatter interaction with firearm propellant gases DOI: To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, University of Illinois at Chicago and Iowa State University researchers explored the influence of propellant gases on blood backspatter. Time instants are shown in a-d, depicting the global backspatter with a magnified view of an individual breakup sequence shown in e-h. Michael, and Alexander L. Yarin In Physics of Fluids, from AIP Publishing, the researchers report using numeric modeling to capture the behavior of gun muzzle gases and predict the reversal of blood droplet flight, which was captured experimentally. Their experiments also show the breakup of blood droplets, a future extension of their modeling efforts. Propellant gases from gunpowder issue from the gun barrel at high speed and form turbulent vortex rings, which can be visualized by high-speed shadowgraph images, like those used to capture flow structures of supersonic aircraft or spacecraft. A penetrating bullet tends to spatter blood droplets from the victim backward, toward the shooter, but a turbulent vortex ring of muzzle gases moving from the shooter toward the victim can reverse the flight of the droplets.

I can not participate now in discussion - there is no free time. I will return - I will necessarily express the opinion.
I can look for the reference to a site on which there are many articles on this question.
It is remarkable, very useful phrase
It agree, rather useful phrase
In it something is. Clearly, many thanks for the help in this question.
