A mathematical model based on viscoelastic fluid (fractional Oldroyd-B model) flow is considered for the peristaltic flow of chyme in small intestine, which is assumed to be in the form of an inclined cylindrical tube. The peristaltic flow of chyme is modeled more realistically by assuming that the peristaltic rush wave is a sinusoidal wave, which propagates along the tube. The governing equati...

Hydroforming is one kind of plasticity working, which can be used to increase the diameter, to change the geometry, or to expand the outer walls of cylindrical shells or tubes. The forming principle of hydroforming is by using a die to constrain the outer geometry of a tube and then pumping high pressure oil into the inner tube, so as to force part of the tube to flow into the die cavity. In or...

This paper investigates the transverse and torsional wave in singleand double-walled carbon nanotubes (SWCNTs and DWCNTs), focusing on the effect of carbon nanotube microstructure on wave dispersion. The SWCNTs and DWCNTs are modeled as nonlocal single and double elastic cylindrical shells. Molecular dynamics (MD) simulations indicate that the wave dispersion predicted by the nonlocal elastic c...

In this work, we studied a pressure-driven flow of a magnetorheological suspension through a cylindrical tube in the presence of a non-uniform magnetic field perpendicular to the tube and varying along its axis. The flow was realized with the help of a commercial capillary rheometer in a controlled-velocity mode. Experimental pressure-flow rate curves exhibited a local minimum, and flow instabi...

In the present work, a device designed for concentrating cells from biological fluids is described. The instrument consists of a tube in which the inner cavity has a conical shape at one of its ends and a small orifice is found at the bottom, while the tube's exterior maintains its cylindrical shape. The tube is placed inside a second tube that ends on a flat surface on which a glass cover slid...

Flybrella is a lightweight inexpensive trap that can be suspended like an upside-down umbrella in prominent locations where house flies, Musca domestica L., rest. It consists of a solid, cylindrical backbone to which is attached a perforated transparent tube, or baffle, with a commercial sugar/toxicant strip affixed inside. Centered directly beneath the tube and also attached to the backbone is...

An integrated process which is proposed for improving dust removal efficiency of cyclones in another paper is considered here for simulation by Artifitial Neural Networks (ANNs) and hybrid ANN and Genetic Algorithm (GA). The process incorporates of two cyclones coupled with a specially designed cylindrical chamber, which includes a rotating tube inside it with air-impinging nozzles drilled on t...

Abstract The purpose of this paper is to study the behavior magnetohydrodynamic (MHD) wave modes that propagate in compressible magnetic flux tubes with an elliptical cross section embedded a environment. dispersion relation describes MHD permitted tube solved numerically. Distortion spatial structure purely real eigenmodes from well-known circular model has been considered. It studied under bo...

We present a numerical investigation of an acoustic sensor based on cylindrical resonator to monitor the properties liquids flowing in tube. The design consists hollow washer surrounding tube, which carries liquid, and can be filled during sensing process. Due impedance mismatch between liquid solid washer, we demonstrate presence high-quality factor resonances associated with (such as velocity...

Transcranial static magnetic field stimulation (tSMS) has inhibitory neuromodulatory effects on the human brain. Most of studies fields have been performed in vitro. To further understand biological mechanisms tSMS, we investigated vivo tSMS motor behavior normal awake rats. The skull a male Wistar rat was exposed and polyethylene tube attached to using dental cement at center cortex (n = 7) or...
