The article considers the problem of vibrations straight sections pipeline based on theory beams. A mathematical model dynamics a viscoelastic pipe with pulsating fluid is developed. speed assumed to be harmonically fluctuating and has following form: V ( t ) = υ 0 (1 + μ 1 cosϖt ). simplified using Bubnov-Galerkin approach solution set common integro-differential equations time as an independe...

In the past, stability of an undamped clamped-pinned pipe conveying fluid has been always considered numerically leading to controversial results. Païdoussis (2004) has shown that a numerical stability analysis of a clamped-pinned pipe requires exceptionally large number of vibration modes to obtain the correct dynamical behaviour. In this paper, analytical proof of stability of a clamped-pinne...

The studies of the behavior of fluid on the nano-level has shown to be an important means of influencing the characteristic of fluid must especially in the area of thermal conductivity. Giving relevance in numerous fields such as biomedicine, manufacturing, fuel cells and soon on. This article considers flow and heat transfer of viscous fluid conveying Gold nanoparticles through expanding or co...
