Splattering

Splattering refers to the dispersion of liquid droplets into a surrounding medium as a result of impact, agitation, or rapid energy transfer. It occurs in everyday situations such as food cooking, as well as in artistic, scientific, and industrial contexts. The appearance of splatter patterns depends on the energy input, properties of the liquid, and the nature of the contacted surface.

Mechanisms include impact splatter, where a liquid drop or jet strikes a surface and breaks apart; shear-induced fragmentation; and atomization from rapid heating or pressure changes. Key liquid properties include viscosity, surface tension, volatility, and temperature. The substrate roughness, porosity, and angle relative to the incoming liquid influence splash height, spread, and directional bias. High speeds and thin liquids tend to produce more numerous, finer droplets; more viscous or cohesive liquids produce fewer droplets with larger sizes.

Applications: In art, splatter painting uses flicked or dripped paint to create textures. In forensic science, bloodstain pattern analysis studies splatter to infer the sequence of events. In cooking and food preparation, splatter of oil or water is common and can be mitigated with lids or splatter screens. In industrial settings, splattering relates to spray coating, aerosolization, or cleaning processes.

Safety and mitigation: Splattering can pose burn or contact hazards when hot liquids or chemicals are involved; protective equipment, splash guards, and containment methods reduce risk. Analytic tools include high-speed videography and microscopy to study patterns; computational models simulate droplet trajectories.
