Nanobubble Collapse Induced Erosion near Flexible and Rigid Boundaries: A Molecular Dynamics Study

In this work, we performed molecular dynamics simulations to study the of a shock wave-induced single nanobubble collapsing near one flexible and two rigid boundaries. The boundary consisted polyethylene, boundaries were made aluminum iron. waves impinging on inside system generated using momentum mirror approach. For relative wall distances, studied shock-induced its collapse atomic velocity contours surrounding collapse-induced damage analyzed. We obtained from ten nanobubbles. Results showed that distance affected nanobubble’s A nanojet was directed surfaces during process. From point view, depth iron, for γ = 1.3 6.0, 0.47 0.63 nm, respectively. It observed extensive occurred only polyethylene boundary.
