Backflow structures in turbulent pipe flows at low to moderate Reynolds numbers
Journal of Fluid Mechanics, 2023 The statistical characteristics and the evolution of the backflow structures are investigated in wall-bounded flows at Reynolds numbers up to $Re_{\tau }=1000$.

Simulations to Eliminate Backflow Power in an Isolated Three-Port Bidirectional DC–DC Converter
Energies, 2022 The aim of this work was to eliminate the backflow power present in an isolated three-port DC–DC converter. Backflow power (which is an inherent property of phase-shifted DC–DC converters) is the major contributor of circulating current the converter ...

Energy backflow in unidirectional spatiotemporally localized wave packets [PDF]
Physical Review A, 2022 Backflow, or retro-propagation, is a counterintuitive phenomenon where for a forward-propagating wave the energy or probability density locally propagates backward.

Spud-Can Penetration Response in Double Layered Soil by Press-Replace Technique [PDF]
Port Said Engineering Research Journal, 2019 One of the most important factors in the process of jack-up rig installation is the good expectation of the amount of spud-can penetration into soil layers under the varying loads.

Flow physics of planar bistable fluidic oscillator with backflow limbs
AIChE journal. American Institute of Chemical Engineers, 2022 Fluidic oscillators (FOs) are used in a variety of applications, including process control and process intensification. Despite the simple design and operation of FOs, the fluid dynamics of FOs exhibit rich complexities. The inherently unstable flow, jet

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

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.

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.

A new approach to quantum backflow [PDF]
, 2005 We derive some rigorous results concerning the backflow operator introduced by Bracken and Melloy. We show that it is linear bounded, self adjoint, and not compact.
