Engineering Applications of Computational Fluid Mechanics, 2022 Most mixed-flow pumps obtain a saddle-like Q-P curve with a backflow, owing to the increased incidence angle at low flow rates. The backflow was developed near the shroud and followed downstream again at its end to form a recirculating flow. The rotating

Thermal backflow in CFTs [PDF]
Physical Review D, 2017 We study the thermal transport properties of general conformal field theories (CFTs) on curved spacetimes in the leading order viscous hydrodynamic limit. At the level of linear response, we show that the thermal transport is governed by a system of forced linearised Navier-Stokes equations on a curved space.

Generation and focusing of a second-order vector beam using a subwavelength optical element
Компьютерная оптика, 2022 This article proposes a new type of subwavelength axicons for creating and focusing second-order vector cylindrical beams. It is also shown that using the proposed subwavelength axicons, it is possible to create focal spots with an energy backflow.

Relativistic quantum backflow [PDF]
Physica Scripta, 2019 Abstract In this paper we discuss relativistic quantum backflow. The general theory of relativistic backflow is presented and it is shown that the backflow can be written as a function of a simple parameter ϵ, which is defined in terms of fundamental constants and the ...

Observation of optical backflow
Optica, 2020 Quantum backflow is a counterintuitive phenomenon in which a forward-propagating quantum particle propagates locally backwards. The actual counter-propagation property associated with this delicate interference phenomenon has not been observed to date in any field of physics, to the best of our knowledge.

An enigmatic route to the contralateral pelvicalyceal system on antegrade pyelogram
Journal of Indian Association of Pediatric Surgeons, 2018 Introduction: The authors present the rare yet enigmatic phenomenon of ‘pyelo-renal’ backflow. Case Presentation: An eight-month-old boy with multiple congenital anomalies underwent left Anderson-Hynes Pyeloplasty for pelvi-ureteric junction obstruction.

Hydrodynamics and sediment transport in Poyang Lake under the effects of wind and backflow
Hydrology Research, 2023 The ecology of the aquatic environment in Poyang Lake, the largest fresh lake in China, is notably impacted by the backflow from the Yangtze River, which conveys a high flux of sediments.
