Mechanism of material deformation during cavitation bubble collapse

This research is devoted to understanding the physical mechanism of cavitation erosion in liquid flows at fundamental scale bubble collapse. Cavitation bubbles form a when pressure decreases locally below saturated vapor pvsat. The grow due low ambient and collapse surrounding increases again above Bubble near solid walls can result high velocity jet shock wave emission that cause loads on wall. These are responsible for erosive damages surfaces, as observed applications like fuel injection, hydrodynamic power generation marine propulsion. On other hand, from collapsing exploited lithotripsy, drug delivery cleaning surfaces. In this work, we follow numerical approach, which begins with development compressible solver capable resolving finite-volume code YALES21 employing simplified homogeneous mixture model. material response resolved finite element Cast3M2. A one–way coupling approach fluid–structure interaction (FSI) simulation between fluid domains pursued. simple field computed by fluid–solid interface communicated computes deformation induced material. end, dynamical events surface highlighted 2D dynamics associated wall estimated. different materials distances discussed.
