Researchers from University of Kashan Report New Studies and Findings in the Area of Computational Materials Science

May 13, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- New research on Computational Materials Science is the subject of a report. According to news reporting out of Kashan, Iran, by VerticalNews editors, research stated, "Vibration of a double visco-elastic carbon nanotubes (CNTs) conveying viscous fluid coupled by visco-Pasternak medium is investigated based on visco-surface nonlocal theory. CNTs are placed in uniform longitudinal magnetic field and modeled by Euler-Bernoulli beam (EBB) theory."

Our news journalists obtained a quote from the research from the University of Kashan, "Visco-CNTs are conveying viscous fluid in which the effect of slip boundary condition is considered using Knudsen number correct factor in Navier-Stokes relations. The higher order governing equations of motion are derived based on Hamilton's principle where differential quadrature (DQ) approach is applied to obtain the nonlocal frequency of coupled visco-CNTs system. The detailed parametric study is conducted, focusing on the combined effects of the magnetic field, visco-Pasternak foundation, Knudsen number, surface effect, aspect ratio, velocity of conveying viscous fluid and direct of fluid velocity. Also, it is found that trend of figures have good agreement with previous researches."

According to the news editors, the research concluded: "The results of this work could be used in design and manufacturing of nano/micro mechanical system in advanced biomechanics applications with magnetic field as a parametric controller."
