In this paper, a Kelvin impulse theory model is constructed for a restricted bubble through
conformal transformation. The collapse dynamics of a restricted bubble near a right-angle …

Tip vortex cavitation (TVC) affects hydrodynamic performance and can cause drastic
vibration and noise; therefore, it is crucial to predict the evolution of TVC, understand its …

The applicability of leading-edge protuberances as a passive flow control approach inspired
by humpback whale flippers has attracted significant research attention in aquatic and …

To suppress the cavitation phenomenon of the fluid machinery under high-velocity flow
conditions, we designed the shark gill slit jet structure based on the principle of bionics. The …

Marine propellers are important propulsion devices for both surface ships and underwater
vehicles. Increasingly severe environmental problems have required further performance …

The scale effect of vortex generators, as microstructures, influences cavitation erosion
remains unclear, posing a key challenge to applying vortex generators in large-scale …

As an essential component of municipal water distribution systems, centrifugal water pumps
are of great significance to achieve urban sustainability. Cavitation is a common …

Partial cavitation has a strong unsteadiness, which will cause serious damage to the
hydraulic machinery. The spanwise obstacle is nearly the most efficient method for …

The finite-time Lyapunov exponent (FTLE) method is a mature and practical method for
analyzing the characteristics of Lagrangian coherent structures. It can be used for studying …

We experimentally confirmed the idea of mitigating (or delaying) the cavitation on the
turbomachinery (rotating blades) by transforming the blade surface to be superhydrophilic …
