Study on Scaling Law of Impact Cratering on Granular Bed
2020
Hosokawa Powder Technology Foundation ANNUAL REPORT
In the present study, we have studied the impact on a granular bed by a hydrogel sphere. The impact of an object will lead to the formation of a crater. The diameter of the crater is proportional to the 1/4 power of the kinetic energy of the object for low speed impact of a solid sphere. For a liquid drop impact cratering, some scaling factors (from 1/6 to 2/5) have been reported due to the complexity of a liquid drop impact phenomenon such as deformation, splashing, and penetrating granular
