Impact characteristics and stagnation formation on a solid

Dec 03, 2019Figures 19(a) and (b) shows the variation of particle impact velocity with respect to particle sphericity and particle diameter, respectively. It is found that a greater particle sphericity rises the particle impact velocity, whereby a round particle (S p = 1) has the highest velocity profile.
