Study of Losses and Energy Efficiency of Hydrostatic Drives with Hydraulic Cylinder

Polish Maritime Research, 2018
Energy efficiency of hydrostatic transmissions, and especially efficiencies of drives with motor speed controlled by throttle, as well as efficiency of hydraulic servomechanisms can in fact be higher than the efficiency values most frequently given by ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Cylinder-Cylinder Attraction in Uniform Flow

Natural Science, 2018
Two cylinders in a uniform flow can attract each other when their separation distance is within the zones of the perturbed velocities of the cylinders. Enhanced perturbed velocity between cylinders causes lowered pressure by Bernoulli’s law. If the cylinders touch or the gap is very small, the flow will work to separate the cylinders.

Dynamic response of a cylinder-plate-cylinder system coupling wake-induced and interference effects

This study proposes a flow-induced vibration (FIV) configuration consisting of two transversely oscillating cylinders with a square plate positioned between them (cylinder–plate–cylinder, C-P-C system) to investigate the coupling between wake-induced and

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Large-eddy simulation of the compressible flow past a wavy cylinder

, 2010
Numerical investigation of the compressible flow past a wavy cylinder was carried out using large-eddy simulation for a free-stream Mach number M? = 0.75 and a Reynolds number based on the mean diameter Re = 2 × 105.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
