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 …

An experimental investigation of the cavitating turbulent flow in a simplified hydraulic turbine
was carried out to examine flow features in a wide range of speed and discharge conditions …

We report on the experimental study of a precessing vortex core (PVC) in an air model of a
Francis turbine. The focus is placed on the modal decomposition of the PVC that occurs in …

Swirl stabilised flows are the most common technology for gas turbine combustion
stabilisation. Although success on the characterisation of these flows is tangible, there are …

Cavitation vortex rope widely occurs in hydraulic machinery, leading to the decrease in
performance characteristic and increase in pressure fluctuation. The objective of this study …

Operating hydraulic turbines under part-or over-load conditions leads to the development of
the precessing vortex rope downstream of the turbine runner. In a regime close to the best …

This paper compares the effect of different angles of triangular conical and truncated conical
regulating valves on the heat and cold separation of vortex tubes. Numerical simulation and …

In a concurrent work, Villois et al.[Phys. Rev. Lett. 125, 164501 (2020) 10.1103/PhysRevLett.
125.164501] reported the evidence that vortex reconnections in quantum fluids follow an …

The paper investigates the unstable behavior of a precessing vortex core in a diffuser
behind a rotating swirler. The studies were carried out by experimental methods using a …

The application of machine learning to solve engineering problems is in extremely high
demand. This article proposes a tool that employs machine learning algorithms for …
