A two-dimensional natural convection flow of a viscous incompressible and electrically conducting fluid with both the viscosity thermal conductivity depending on temperature past vertical impermeable flat plate is considered in presence uniform transverse magnetic field. The governing equations are reduced to non-similar boundary layer by introducing coordinate transformations appropriate cases...

The nonlinear density variation with temperature happens in many thermal applications like solar collectors, energy production, heat exchangers, and combustions, it gives a significant impact on transfer fluid flows. Thus, convective of an unsteady stagnation point flow under the influence gravity modulation presence water-based nanoparticles alumina (Al2O3) is studied here. Suitable variables ...

The Keller-Segel model is a system of partial differential equations modelling chemotactic aggregation in cellular systems. This model has blowing up solutions for large enough initial conditions in dimensions d ≥ 2, but all the solutions are regular in one dimension; a mathematical fact that crucially affects the patterns that can form in the biological system. One of the strongest assumptions...

Abstract. In this paper, the Soret and Dufour effects on the steady, laminar mixed convection heat and mass transfer along a semi-infinite vertical plate embedded in a non-Darcy porous medium saturated with micropolar fluid are studied. The governing partial differential equations are transformed into ordinary differential equations. The local similarity solutions of the transformed dimensionle...

The steady, two dimensional flow of an incompressible micropolar fluid near the stagnation point on a vertical plate with prescribed surface heat flux is studied. The free stream velocity and the surface heat flux are assumed to be proportional to the distance from the stagnation point. Similarity transformation is employed to transform the governing partial differential equations to a set of o...

Submitted: May 15, 2013; Accepted: Jun 23, 2013; Published: Jul 22, 2013 Abstract: Stagnation-point flow of a nanofluid over a nonlinear stretching sheet is investigated theoretically when the sheet is stretched with a power law velocity under a constant wall temperature. The governing nonlinear problem incorporates the effects of Brownian motion and thermophoresis is transformed by using appro...
