“…In contrast on certain physical situations, the surface may be stretched suddenly from the rest and the transient or unsteady aspects become important. However, the number of studies on unsteady flow due to stretching surface is very limited (Surma Devi et al [34], Lakshmisha et al [35], Takhar et al [36], Pop and Nath, [37], Chamkha and Issa [38], Ishak et al [39]). The comprehensive analysis on unsteady mixed convection flow due to a stretching semi-infinite vertical plate in a parallel free stream is also important to be investigated and such studies are yet to appear in the literature.…”

Our aim in this article is to investigate numerically the unsteady two-dimensional mixed convection flow along a vertical semi-infinite stretching sheet in a parallel free stream with a power-law wall temperature and concentration distributions of the form T w (x) = T ∞ + Ax 2m−1 and C w (x) = C ∞ + Bx 2m−1 , where A, B and m are constants. The unsteadiness in the flow is caused by the time dependent stretching sheet as well as by the free stream velocity. The governing nonlinear partial differential equations in the velocity, temperature and concentration fields are written in nondimensional form using suitable transformations. The final set of resulting coupled nonlinear partial differential equations is solved using an implicit finite-difference scheme in combination with a quasi-linearization technique. The effects of various governing parameters on the velocity, temperature and concentration profiles as well as on the skin friction coefficient, local Nusselt number and local Sherwood number are presented and discussed in details. The computed numerically results are compared with previously reported work and are found to be in excellent agreement.

SUMMARYThis paper looks at the unsteady three-dimensional MHD flow of an elastico-viscous fluid over a stretching surface. The analysis of mass transfer is also analyzed. The governing boundary layer equations are reduced into partial differential equations with three dependent variables through similarity transformations. The transformed system of equations is solved analytically by employing homotopy analysis method (HAM). Plots for various interesting parameters are presented and discussed. Numerical data for surface shear stresses and surface mass transfer in steady case are also tabulated.

“…Nowar [14] solved the problem of peristaltic flow of a nanofluid in the regime of Hall current and porous medium. A vast study exploring different aspects of nanofluid may be consulted in the references [15][16][17][18][19][20][21][22][23].…”

Abstract:The magnetohydrodynamic thin film nanofluid sprayed on a stretching cylinder with heat transfer is explored. The spray rate is a function of film size. Constant reference temperature is used for the motion past an expanding cylinder. The sundry behavior of the magnetic nano liquid thin film is carefully noticed which results in to bring changes in the flow pattern and heat transfer. Water-based nanofluids like Al 2 O 3 -H 2 O and CuO-H 2 O are investigated under the consideration of thin film. The basic constitutive equations for the motion and transfer of heat of the nanofluid with the boundary conditions have been converted to nonlinear coupled differential equations with physical conditions by employing appropriate similarity transformations. The modeled equations have been computed by using HAM (Homotopy Analysis Method) and lead to detailed expressions for the velocity profile and temperature distribution. The pressure distribution and spray rate are also calculated. The comparison of HAM solution predicts the close agreement with the numerical method solution. The residual errors show the authentication of the present work. The CuO-H 2 O nanofluid results from this study are compared with the experimental results reported in the literature showing high accuracy especially, in investigating skin friction coefficient and Nusselt number. The present work discusses the salient features of all the indispensable parameters of spray rate, velocity profile, temperature and pressure distributions which have been displayed graphically and illustrated.
