As a fundamental topology-transforming event, reconnection plays a significant role in the
dynamics of plasmas, polymers, DNA, and fluids—both (classical) viscous and quantum …

The spectral/hp element method combines the geometric flexibility of the classical h-type
finite element technique with the desirable numerical properties of spectral methods …

Cavitation within a tip leakage flow remains a challenging issue in a variety of axial
hydraulic machines. It is still not possible nowadays to predict cavitation occurrence in such …

This paper investigates the effect of gap size on the inception of tip leakage vortex cavitation
(TLVC) with a hybrid Eulerian–Lagrangian model. Good agreement is achieved between the …

The three-dimensional dynamic behaviour of a tip vortex generated by a NACA-415
hydrofoil is investigated under wetted flow and cavitating conditions using time-resolved …

Air-core vortices are a ubiquitous phenomenon in the intakes of hydropower stations. Due to
the transient and instability of two-phase vorticial flow, the prediction of air-core vortex …

In this paper, the noise characteristics of tip leakage vortex cavitation (TLVC) inception are
numerically investigated using a previously developed hybrid Eulerian–Lagrangian model …

The vortex dynamics of leading-edge vortices on plunging high-aspect-ratio (AR= 10) wings
and airfoils were investigated by means of volumetric velocity measurements, numerical …

The present study investigates the complex vortex interactions in two-dimensional flow-field
behind a symmetric NACA0012 airfoil undergoing a prescribed periodic pitching-plunging …

The essence of turbulent flow is the conveyance of energy through the formation, interaction,
and destruction of eddies over a wide range of spatial scales—from the largest scales where …
