Dynamics of the impact of a drop on a solid surface

Mechanism of the effect of drops of suspension on the surface of parts in hydroabrasive treatment

“…Engel [6] believes that the radial speed of the spreading is I0 times as high as the initial speed of impact, in [7] it is 2.65 times, and in [8] 8 times. On the basis of the presented results of numerical calculations, and also in view of the experimental data [Ii] it can apparently be assumed in calculations that the speed of radial spreading of the drop is 5-6 times as high as the speed of impact; this also corresponds to the mean speeds of the jet adopted for hydroabrasive treatment.…”

“…Numerical methods were also applied in the investigation of the dynamics of impact of a drop [8]. The main stages of the dynamics of interaction of a flying drop with the surface of the treated part [6][7][8][9][10][11] at the above-mentioned speeds can be represented in the following way.…”
