Three dimensional flow of non-Newtonian viscoelastic fluid with the variation in the viscosity over a stretching surface is investigated. The governing partial differential equations of continuity, momemtum, energy and concentration are transformed into nonlinear ordinary differential equations by using similarity transformations. The transformed equations are solved numerically by fourth-order...

This paper deals with the analysis of an unsteady mixed convection flow of a fluid saturated porous medium adjacent to heated/cooled semi-infinite stretching vertical sheet in the presence of heat source. The unsteadiness in the flow is caused by continuous stretching of the sheet and continuous increase in the surface temperature. We present the analytical and numerical solutions of the proble...

An enzyme-incorporated hydrogel made of alginate and polyacrylamide shows a linearly increased activity with the enlargement of surface area upon stretching.

Large-strain elastic superhydrophobicity is highly desirable for its enhanced use performance and functional reliability in mechanically dynamic environments, but remains challenging to develop. Here we have, for the first time, proven that an elastic fibrous membrane after surface hydrophobization can maintain superhydrophobicity during one-directional (uniaxial) stretching to a strain as high...

We study the efficiency of shrinking/stretching radiative fins to improve heat transfer rate. To evaluate competence suggested fins, influence shrinking/stretching, thermogeometric parameters, surface temperature, convection conduction, radiation and Peclet number is investigated. The problem solved numerically using a shooting method. validate numerical solution, results are compared with solu...

abstract background: restless leg syndrome prevalence is high among the patients undergoing hemodialysis. due to several side effects of medicational treatments, the patients prefer non-medicational methods. therefore, the present study aimed to investigate the effects of two methods of reflexology and stretching exercises on the severity of restless leg syndrome among patients undergoing hemod...

Steady two dimensional MHD stagnation point flow of a power law fluid over a stretching surface is investigated when the surface is stretched in its own plane with a velocity proportional to the distance from the stagnation point. The fluid impinges on the surface is considered orthogonally. Numerical and analytical solutions are obtained for different cases.

Boundary Layer Flow past a stretching surface with constant wall temperature, of a nanofluid is studied for heat transfer characteristics. The system of partial differential equations describing such a flow is subjected to similarity transformations gives rise to a boundary value problem involving a system of ordinary differential equations. This system is solved by a shooting method. Effect of...

The normal impingement of axisymmetric Homann stagnation-point flow on a surface executing perpendicular, planar, biaxial stretching is studied. field generated an exact solution the steady, three-dimensional Navier–Stokes equations in form similarity solution. It shown that two sets dual solutions exist, forming four different branches steady solutions. For sufficiently small stretches (includ...
