Ricci flow coupled with harmonic map flow [PDF]
, 2011 We investigate a new geometric flow which consists of a coupled system of the Ricci flow on a closed manifold M with the harmonic map flow of a map phi from M to some closed target manifold N with a (possibly time-dependent) positive coupling constant ...

Lagrangian Flow Network approach to an open flow model [PDF]
, 2017 Concepts and tools from network theory, the so-called Lagrangian Flow Network framework, have been successfully used to obtain a coarse-grained description of transport by closed fluid flows.

Stream lamination and rapid mixing in a microfluidic jet for X-ray spectroscopy studies
Flow, 2023 Microfluidic mixers offer new possibilities for the study of fast reaction kinetics down to the microsecond time scale, and methods such as soft X-ray absorption spectroscopy are powerful analysis techniques.

Parity flow as ${\mathbb Z}_2$-valued spectral flow [PDF]
, 2019 This note is about the topology of the path space of linear Fredholm operators on a real Hilbert space. Fitzpatrick and Pejsachowicz introduced the parity of such a path, based on the Leray-Schauder degree of a path of parametrices.

Is a baseball like knuckleball possible in cricket?
Flow, 2023 The knuckleball is considered to be one of the hardest pitches to hit in baseball due to its seemingly unpredictable motion. It has gained popularity in cricket in recent times.

Acoustofluidic semen analysis for veterinary male bovine infertility assessment
Flow, 2023 We demonstrate through the use of a unique acoustically driven microfluidic extensional rheometry platform (ADMiER) that a single measurement – i.e. the time required for a liquid bridge filament comprising a microlitre semen sample to thin and break up ...

Wind speed inference from environmental flow–structure interactions
Flow, 2021 This study aims to leverage the relationship between fluid dynamic loading and resulting structural deformation to infer the incident flow speed from measurements of time-dependent structure kinematics.

Geodesic Flows Modelled by Expansive Flows
Proceedings of the Edinburgh Mathematical Society, 2018 AbstractGiven a smooth compact surface without focal points and of higher genus, it is shown that its geodesic flow is semi-conjugate to a continuous expansive flow with a local product structure such that the semi-conjugation preserves time parametrization. It is concluded that the geodesic flow has a unique measure of maximal entropy.

Large eddy simulation of aircraft at affordable cost: a milestone in computational fluid dynamics
Flow, 2021 While there have been numerous applications of large eddy simulations (LES) to complex flows, their application to practical engineering configurations, such as full aircraft models, have been limited to date.

Drop-on-demand painting of highly viscous liquids
Flow, 2021 An on-demand painting system with a simple structure device that ejects highly viscous liquids as microjets is introduced. An impulsive motion of the container results in the ejection of a viscous liquid jet from the nozzle.
