abstract
this paper presents the jeffery hamel flow of a non-newtonian fluid namely casson fluid. suitable similarity transform is applied to reduce governing nonlinear partial differential equations to a much simpler ordinary differential equation. variation of parameters method (vpm) is then employed to solve resulting equation. same problem is solved numerical by using runge-kutta order 4 method. a comparison between both the solutions is carried out to check the efficiency of vpm. effects of emerging parameters are demonstrated both for diverging and converging channels using graphical simulation.

full textEntropy generation analysis of non-newtonian fluid in rotational flow
The entropy generation analysis of non-Newtonian fluid in rotational flow between two concentric cylinders is examined when the outer cylinder is fixed and the inner cylinder is revolved with a constant angular speed. The viscosity of non-Newtonian fluid is considered at the same time interdependent on temperature and shear rate. The Nahme law and Carreau equation are used to modeling dependenc...
full textAnalytical Investigation of MHD Jeffery–Hamel Nanofluid Flow in Non-Parallel Walls
In this paper, Homotopy perturbation method (HPM) has been applied to investigate the effect of magnetic field on Cu-water nanofluid flow in non-parallel walls. The validity of HPM solutions were verified by comparing with numerical results obtained using a fourth order Runge–Kutta method. Effects of active parameters on flow have been presented graphically. The results show that velocity i...
full textNewtonian heating and magnetohydrodynamic effects in flow of a Jeffery fluid over a radially stretching surface
The combined effects of Newtonian heating and magnetohydrodynamics (MHD) in a flow of a Jeffery fluid are analyzed in stagnation point flow over a radially stretching surface. The governing equations are modeled by invoking boundary layer analysis. The computed solution by a homotopy approach is valid in the spatial domain. Graphical results for the velocity and temperature fields are displayed...
full textNon-Newtonian Fluid Flow through Fabrics
Abstract The flow of a fluid through textiles has been studied for a number of years. Understanding the flow phenomena along with the corresponding environmental changes (pressure drop, concentration gradient, etc.) becomes important in many fields, such as liquid transport through geomembranes, effluent movement through filtration devices, and chemical movement through protective apparel. This...
full textA Case Study of Elliptic Functions in a CAS: Jeffery-Hamel Flow with Maple
Elliptic functions and integrals are not as widely known in the scientific populace as they have been in the past, even though they can still be used to solve an impressive array of applied problems. Computer Algebra Systems (CAS) have stepped into this knowledge gap and claim to provide access to many of the formulae that have proven so useful. This paper takes a classical problem in two-dimen...
