Design method of a vertical screw conveyor based on Taylor–Couette–Poiseuille stable helical vortex

open access: yesAdvances in Mechanical Engineering, 2017
This article investigates gas–solid two-phase flow in a vertical screw conveyor and analyzes the distribution function of the circumferential velocity of particles in the radial direction.

Thermal Radiation and Chemical Reaction Effects on Unsteady Magnetohydrodynamic Third Grade Fluid Flow Between Stationary and Oscillating Plates

open access: yesInternational Journal of Applied Mechanics and Engineering, 2019
An analysis was carried out for an unsteady magnetohydrodynamic(MHD) flow of a generalized third grade fluid between two parallel plates. The fluid flow is a result of the plate oscillating, moving and pressure gradient.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Contribution of advetion, turbulent transport and diffusion terms to Nusselt number and torque coefficient in Taylor-Couette flow

open access: yesJournal of Thermal Science and Technology, 2016
Contributions of the advection, turbulent transport and diffusion terms to the Nusselt number and the torque coefficient in the Taylor-Couette flow were evaluated. Integrating the energy equation in the Taylor-Couette flow twice gave an equation in which

Caribbean plate tilted and actively dragged eastwards by low-viscosity asthenospheric flow

open access: yesNature Communications, 2021
Here, the authors follow a new approach using analytic solutions for Poiseuille-Couette channel flow to compute asthenospheric viscosities under the Caribbean.

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Rheological Characterization of Yield-Stress Materials: Flow Pattern and Apparent Wall Slip

open access: yesApplied Rheology, 2015
An experimental and numerical investigation of the rotational rheometry of yield-stress materials is performed, using waterbased Carbopol dispersions. The flow and fluid characterization in different rheometer geometries, namely the smooth Couette, the ...
