Jets from Shocked Metal Surfaces with Ridges

This paper explores the dynamics of ejecta resulting from shock-induced perturbations in defected metal surfaces. An analysis of the outflow mass and its maximum velocity aims to establish a relationship between the geometry of the defect and the behavior of the ejecta. By varying the aspect ratio (height to width ratio) and volume in distinct experiments, the study aims to assess how the height of the defect and its total volume influence the jetting characteristics. The paper will explore the influence of ridge geometry on ejecta mass and velocity, comparing triangular and sinusoidal ridges to clarify how changes in ridge parameters affect the jetting phenomena.
