Applications of the vortex-surface field to flow visualization, modelling and simulation

Flow, 2023
We review the progress on the applications of the vortex-surface field (VSF). The VSF isosurface is a vortex surface consisting of vortex lines. Based on the generalized Helmholtz theorem, the VSF isosurfaces of the same threshold at different times have

Thermal bootstrap of matrix quantum mechanics

Journal of High Energy Physics
We implement a bootstrap method that combines stationary state conditions, thermal inequalities, and semidefinite relaxations of matrix logarithm in the ungauged one-matrix quantum mechanics, at finite rank N as well as in the large N limit, and ...

Unsteady flow behaviour of multi-rotors in ground proximity

Flow, 2023
The unsteady flow behaviour of two side-by-side rotors in ground proximity is experimentally investigated. The rotors induce a velocity distribution interacting with the ground causing the radial expansion of the rotor wakes.

Shaping liquid films by dielectrophoresis

Flow, 2021
We present a theoretical model and experimental demonstration of thin liquid film deformations due to a dielectric force distribution established by surface electrodes. We model the spatial electric field produced by a pair of parallel electrodes and use

Isotopic lifting of analytic and quantum mechanics

Revista Técnica de la Facultad de Ingeniería, 2011
In a preceding article we have introduced the isotopies of the differential calculus and of Newton's equations of motion. In this second paper we use these results lo construct the isotopies of analytic and quantum mechanics.

Digital twin of a large-aspect-ratio Rayleigh–Bénard experiment: role of thermal boundary conditions, measurement errors and uncertainties

Flow
Albeit laboratory experiments and numerical simulations have proven themselves successful in enhancing our understanding of long-living large-scale flow structures in horizontally extended Rayleigh–Bénard convection, some discrepancies with respect to ...

Solidity effects on the performance of vertical-axis wind turbines

Flow, 2021
The variety of configurations for vertical-axis wind turbines (VAWTs) make the development of universal scaling relationships for even basic performance parameters difficult.

A review on vortex dynamics in the healthy and dilated left ventricles and its application to heart health

Flow
Many cardiovascular diseases occur due to an abnormal functioning of the heart. A diseased heart leads to severe complications and in some cases death of an individual.

Flow forth

Flow, 2021
The study of fluid flow has enabled milestones in technology and a deeper understanding of the natural world. Existing journals cover fundamental aspects of fluid mechanics very well and other journals target specific application fields.

Real-time flow measurement system: physics-informed reconstruction and sampling strategy

Flow, 2023
In this work, we focus on a multi-hole pressure-probe-based flow measurement system for wind tunnel measurements that provides real-time feedback to a robot probe-manipulator, rendering the system autonomous. The system relies on a novel, computationally
