In the set of experiments, parameters such as … Witryna14 sie 2024 · As the sphere penetrates, the fabric is drawn inward, providing a fabric funnel through which a Worthington jet subsequently passes. We show that the presence of fabric increases the drag at entry and enables air-entraining cavities otherwise unattainable by hydrophilic spheres for the impact speeds tested.

While the solid sphere is an extended object, we will assume that the projectile is a point-like mass. In this case, it is clear that if the incoming projectile has an impact parameter larger than R, it will not be de ected at all, while if the impact parameter is less than R, it may su er a relatively extreme de ection. tssaa graphics
