A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Non-Invasive Pulmonary Artery Wave Intensity Analysis in Pulmonary Hypertension.

, 2015
Pulmonary wave reflections are a potential hemodynamic biomarker for pulmonary hypertension (PH) and can be analyzed using wave intensity analysis (WIA). In this study we used pulmonary vessel area and flow obtained using cardiac magnetic resonance (CMR)

Numerical simulations for matter transport by the interaction between bubbles and pressure waves near tissue boundaries

Journal of Fluid Science and Technology
The interaction between bubbles and tissues (bone and fat) in ultrasound and the mechanism of drug transport accompanied by bubble collapse were investigated numerically by using the ghost fluid methods with zonal grids.

Research on Clearance Area of Single Track Tunnel for Medium and Low Speed Maglev Traffic Based on Passenger Pressure Comfort

机车电传动, 2020
The rapid train passing through the tunnel will cause severe pressure wave phenomenon, which will lead to the problem of passengers' ear discomfort. In order to reduce the severe pressure wave and ensure the comfort of passengers, it is necessary to make

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Research on Pressure Load Characteristics of 600 km/h Single Maglev Train Passing Through Tunnel

机车电传动, 2020
In an instant, when the train enters the tunnel from the open line, the air flow space around the train suddenly becomes smaller, and the air in front of the train is compressed and the air pressure increases sharply, forming an initial compression wave,

Numerical simulation of pressure variation during train passage in tunnel

Nihon Kikai Gakkai ronbunshu, 2015
When a train travels through a tunnel at high speed, large pressure variations, which act on tunnel lining, equipments inside the tunnel, and the train, are generated in the tunnel.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
