Two experimental devices for examining liquid jet impingement on a high-speed moving surface are described: an air cannon device and a spinning disk device. The apparatuses are used to determine optimal approaches to the application of liquid friction modifier (LFM) onto rail tracks for top-of-rail friction control.

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

Pooled DNA sequencing is a fast and cost-effective strategy to detect rare variants associated with complex phenotypes in large cohorts. Here we describe the computational analysis of pooled, next-generation sequencing of 32 cancer-related genes using the SPLINTER software package. This method is scalable, and applicable to any phenotype of interest.
FAQs
Inertia provides the dominant driving force immediately after the drop contacts the pool, pushing liquid outward and downward and creating a transient crater. The resulting deformation depends strongly on impact velocity and drop size because both influence the strength of the incoming motion. Examining crater formation therefore helps engineers assess how forceful impacts alter liquid transport and surface response.
Viscosity and surface tension oppose the spreading driven by inertia, but they do so in different ways. Viscosity resists liquid motion, while surface tension works to restore the liquid interface. Their relative influence helps determine whether the impact produces rebound, jetting, or other transient behavior. These properties are therefore essential when comparing liquids or predicting process outcomes.
Pool depth affects how the impact disturbance develops within the receiving liquid and can influence the resulting deformation and air entrainment. Because the same drop and impact conditions may interact with different liquid volumes, depth should be treated as an important experimental or design variable. Accounting for it improves interpretation of splashing, mixing, and transient surface behavior.
A useful analysis should consider impact velocity, drop size, liquid viscosity, surface tension, and pool depth. These variables collectively determine how inertia competes with resistance to deformation and how the event develops after contact. Recording their effects on crater formation, spreading, rebound, jetting, splashing, and air entrainment allows engineers to connect operating conditions with observable outcomes.
Impact studies help engineers evaluate what happens when droplets from spray systems or fuel injectors reach a liquid surface. By relating velocity, drop size, and liquid properties to spreading, splashing, mixing, or air entrainment, they can better anticipate fluid transport under dynamic conditions. This supports design decisions where droplet behavior influences delivery and downstream liquid handling.
The findings are relevant to coating and printing processes, liquid-handling equipment, and surfaces exposed to droplets. In these settings, engineers may need to control or predict splashing, mixing, erosion, or fluid transport. Studying the transient response of the liquid surface provides a basis for evaluating how operating conditions and liquid properties affect process performance.
