Implication

This analysis evaluates the impact of nozzle configuration on cavitating jets and erosion intensity, suggesting design improvements for engineering applications.

Key Points

Enhanced nozzle configurations significantly improve cavitation-induced erosion in submerged jets.
High-speed visualization reveals periodic cloud shedding and vortex fragmentation in impinging jets.
Proper orthogonal decomposition analysis captures stronger large-scale fluctuations due to nozzle expansion.
Wall impingement promotes energy concentration in low-order modes, impacting flow structure dynamics.
