Mean flow of turbulent–laminar patterns in plane Couette flow [PDF]

, 2007
A turbulent–laminar banded pattern in plane Couette flow is studied numerically. This pattern is statistically steady, is oriented obliquely to the streamwise direction, and has a very large wavelength relative to the gap. The mean flow, averaged in time

Simulation of Three-Dimensional Flow Field around Unconventional Bridge Piers [PDF]

Eurasian Journal of Science and Engineering, 2017
The study presents a three-dimensional numerical simulation of turbulent flow field around unconventional bridge piers which are downstream-facing round- nosed (DS-FRNP) and upstream- facing round- nosed (US-FRNP) and are compared with a circular pier in

Turbulent energy motion of fiber suspensions in a rotating frame

Alexandria Engineering Journal, 2021
Turbulent flows play a major role in many fields of science and industry. Noticeable attention is seen on turbulent flows of suspending fibers because of the sensitivity of the electrical, thermal, and mechanical properties of the connecting fiber ...

Numerical study of turbulent flow under different flow mixing devices in a scaled-down reactor pressure vessel model

Nuclear Engineering and Technology
Turbulent flow in reactor pressure vessel (RPV) of pressurized water reactor (PWR) is complicated because the complex geometry in RPV. The flow rates through fuel assemblies at core inlet are strongly influenced by different designs of flow mixing ...

On Flow Reversal in Turbulent Swirling Flow

Journal of the Physical Society of Japan, 2003
Summary: A turbulent swirling flow is studied with the aid of a variational method. The mean-flow field is expressed by the mean vorticity proportional to its curl. The total axial flux and total helicity per unit length are introduced to characterize the swirling flow, and the condition for the reversal of the axial flow near the center of flow is ...

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...

Synthesis of patient-specific multipoint 4D flow MRI data of turbulent aortic flow downstream of stenotic valves

Scientific Reports, 2022
We propose to synthesize patient-specific 4D flow MRI datasets of turbulent flow paired with ground truth flow data to support training of inference methods.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Transitions of turbulent superstructures in generalized Kolmogorov flow

Physical Review Research, 2021
Self-organized large-scale flow structures occur in a wide range of turbulent flows. Yet, their emergence, dynamics, and interplay with small-scale turbulence are not well understood.
