Abstract In this paper, the front-end circuit of a capacitance wire-mesh sensor (WMS) is analyzed in detail and new methodology to tune its feedback gains reported. This allows, for first time, WMS be able provide linear measurements multiphase fluids with electrical conductivity greater than 100

This study deals with the development of a numerical wire mesh screen model for unsteady simulation aeroacoustic configurations. Such devices are indeed growing interest practical applications because they potentially lead to significant noise-reduction effects. Numerical simulations including screens therefore major optimize their possible location and properties, as well get better understand...

Introduction: Ferrocement is a low-cost material that can be utilized as replacement for expensive fiber-reinforced polymer (FRP), which generally used retrofitting structural and non-structural reinforced concrete members. The objective of this paper to investigate the effectiveness wire mesh in flexural members such beams. It also investigated capacity beams, are with partial or complete regu...

Fog represents a large untapped source of potable water, especially in arid climates. Numerous plants and animals use textural and chemical features on their surfaces to harvest this precious resource. In this work, we investigate the influence of the surface wettability characteristics, length scale, and weave density on the fog-harvesting capability of woven meshes. We develop a combined hydr...

In this work, polyimide (PI) was coated onto an ultrafine gilt molybdenum wire in order to protect the gilt surface and prepare an electrically stable wire mesh material which can be widely used in space. The surface of the PI-coated gilt molybdenum wires was characterized using FTIR, SEM, and EDS. Factors such as temperature stability of the PI coating, mechanical properties of the PI-coated g...

A true bronchial dosimeter has been designed, consisting of four 400-mesh wire screens and a filter paper. With a face velocity of 3.3 cm s(-1) for home exposure and 4.6 cm s(-1) for mine exposure, the deposition pattern on the wire screens were found to satisfactorily match the variation of the dose conversion factor (in units of mSv WL M(-1)) with the size of radon progeny from 1 to 1000 nm. ...

Passive flow control techniques are needed to reduce separation and enhance aerodynamic performance. In this work, the effect of a knitted wire mesh on backward-facing ramp was numerically investigated for Reynolds number 3000. A grid independence study RANS turbulence model sensitivity analysis were conducted. The CFD simulations exhibited counter-rotating streamwise vortices emerging from mes...

In this work a catalyst consisting of high surface area ZnO nanoflowers supported on a stainless steel wire mesh was synthesized by hydrothermal growth, and tested for the catalytic photodegradation of methylene blue under UV irradiation. The stability of the photocatalyst was evaluated by assessing the evolution over several reaction stages of catalytic activity and ZnO loss. The initial high ...

Here, we report the use of microwire and mesh working electrodes in paper analytical devices fabricated by origami paper folding (oPADs). The important new result is that Au wires and carbon fibers having diameters ranging from micrometers to tens of micrometers can be incorporated into oPADs and that their electrochemical characteristics are consistent with the results of finite element simula...
