Coefficient of restitution and dimensions of surface deformations for particle-wall collisions in various fluids

Description

Controlled particle-wall collisions are conducted in various fluids. Impact and rebound velocities of a particle as well as the diameter and depth of the generated crater on the surface are reported in this dataset. Three materials are used for the walls: aluminum alloys 6061, 2014, and 7075. The impact experiments are performed in seven fluids with a wide range of density and viscosity: air and six different mixtures of water-glycerin. Properties of the impacting particle, target surfaces, and fluids are given in the PhD dissertation: Ruiz-Angulo, Angel (2008) Surface Deformation in a Liquid Environment Resulting from Single Particle Collisions. Ph.D. Dissertation, California Institute of Technology. http://resolver.caltech.edu/CaltechETD:etd-05222008-090253. Concise description of the experimental procedure, material properties, results, and analyses are also given in the following article: Ruiz-Angulo, A., Roshankhah, S., and Hunt, M. L. "Surface deformation and rebound for normal particle-wall collisions in a surrounding fluid." under review in the Journal of Fluid Mechanics.
