TL;DR: In this article, the transient response of an upper-convected Maxwell fluid flow in a circular tube is analyzed by variational approach of Kantorovich and the method of finite difference.
Abstract: The transient response of an upper-convected Maxwell fluid flow in a circular tube is analysed by variational approach of Kantorovich and the method of finite difference. The solution of the variational method is in agreement with the numerical results by the difference schemes. The results show that the method of Kantorovich is suitable for the study of non-steady flow of non-Newtonian fluids and the effect of elasticity of the fluid has an influence on the non-steady flow.

TL;DR: In this paper, a D-dimensional cosmological model describing the evolution of a perfect fluid with negative pressure (x-fluid) and a fluid possessing bothsh ear and bulk viscosity in n Ricci-flat spaces is investigated.
Abstract: A D -dimensional cosmological model describing the evolution of a perfect fluid with negative pressure (x-fluid) and a fluid possessing bothsh ear and bulk viscosity in n Ricci-flat spaces is investigated. The second equations of state are chosen in some special form of metric dependence of the shear and bulk viscosity coefficients. The equations of motion are integrated, and the dynamical properties of exact solutions are studied. It is shown that the 2-component model, where the x-fluid plays the role of a quintessence and the viscous fluid is used as cold dark matter, is free from the cosmic coincidence problem.

TL;DR: In this article, a peristaltic flow in a tube has been carried out taking into account the non-Newtonian fluid : Rabinowitsch fluid model, and solutions have been derived for fluid flow in axial direction in terms of pressure gradient.
Abstract: With the development of medical science, non-Newtonian fluids have taken on added significance with a variety of applications in real life. The flow of non-Newtonian fluids in tubes and pipes plays a vital role in daily life. The examples of such applications are medical instruments, human body, machines, etc. The study of such mechanisms with the Newtonian fluids has not been found satisfactory due to nonlinear behavior of stress strain relationship. In the present analysis, the study of peristaltic flow in a tube has been carried out taking into account the non-Newtonian fluid : Rabinowitsch fluid model. Considering the significant terms in Navier-Stokes equations, solutions have been derived for fluid flow in axial direction in terms of pressure gradient. Using the continuity of flow, and exact solution has been derived for fluid pressure at wall. To establish the applicability of the solution, results for pressure rise at wall, pressure gradient and streamlines have been presented graphically.

TL;DR: In this article, a new rheological model was applied to the analysis of the electrorheological behavior of a fluid containing silica nanoparticle-decorated polyaniline nanofibers.
Abstract: A new rheological model was applied to the analysis of the electrorheological behavior of a fluid containing silica nanoparticle-decorated polyaniline nanofibers. A model’s predictions were compared with the experimental data, revealing that the proposed model correctly predicted the shear stress behavior both quantitatively and qualitatively. The shear stress data of the electrorheological fluid showing aligned fibers’ structural reformation as a function of the shear rate agreed well with the new model which required fewer parameters than the CCJ (Cho–Choi–Jhon) model. The static yield stress was found to be quadratically dependent on the field strength, in agreement with the predictions of the polarization model. A scaling function was used to model the yield stress behavior of the electrorheological fluid over a range of electric fields, and it correctly predicted the static yield stress behavior both quantitatively and qualitatively.
