Fluid–structure modelling for material deformation during cavitation bubble collapse

The dynamics of cavitation bubbles and their interaction with solids has been studied for long, mostly on the macro-scale sheet vortex cavitation. Erosion takes place small, concentrated areas solid walls exposed to One-way fluid structure (FSI), in which feedback material deformation is not considered, provides an adequate understanding underlying mechanism. However, practical applications motion can significantly affect bubble dynamics. This will, principle, alter structural loading, stresses erosion solid. In this paper, we will report comparisons one-way two-way coupled FSI modelling using our finite volume based solver YALES21 element Cast3M.2 coupling, wall considered domain. To do so, develop a compressible Arbitrary Lagrangian–Eulerian formulation equip it moving mesh capabilities order maintain continuous fluid–solid We present results step-wise coupling approach analyse effects due response damping impact pressures by different materials. Finally, discuss need characteristics nearby bubbles.
