The paper addresses the influence of non-uniform heat source/sink in flow of couple stress fluid by a stretching cylinder in a thermally stratified medium. Thermal radiation effect in heat transfer analysis is also accounted. Conservation laws of mass, linear momentum and energy leads to nonlinear situation. Use of adequate transformations coverts the partial differential equations into the ordinary differential equations. Series solutions of the resulting equations are obtained for the velocity and temperature. Convergence of the solutions is explicitly checked. Impacts of various sundry variable son the velocity, temperature, wall shear stress and Nusselt number are examined through graphical illustrations and numerical values. The effect of β and Re on velocity field is qualitatively similar. For larger values of curvature parameter γ velocity enhances. Influences of S and R on temperature on the temperature distribution are opposite. Heat transfer at the surface decays when A and B increase.

Original scientific paper https://doi.org/10.2298/TSCI170911279AIn this paper, the effect of convective boundary conditions, heat generation, Brownian motion, and thermophoresis on heat transfer characteristics of a moving cylinder embedded into cooling medium consists of water with nanoparticles are studied. The governing boundary-layer equations transformed to ODE using similarity transformation method and then solved analytically using optimal homotopy asymptotic method for the general case. The velocity, temperature, and concentration profiles within the boundary-layer plotted and discussed in details for various values of the different parameters. Moreover, the effect of boundary-layer behavior on the surface shear stress, rate of heat and mass transfer investigated.

Abstract. The article is focused on the effects of Soret and chemical reaction on MHD free convection flow through a vertical porous surface in the presence of heat source, viscous dissipation and radiation. The dimensionless governing equations for this investigation are solved analytically using perturbation technique. Numerical evaluation of the numerical results is performed and the results for velocity, temperature and concentration profiles within the boundary layer are discussed and shown graphically. Also skin-friction coefficient due to velocity, Nusselt number coefficient due to temperature and Sherwood number coefficient due to concentration fields are evaluated.Keywords: Boundary layer; MHD; Radiation; Viscous dissipation; Chemical reaction; Permeability of porous; Heat source. IntroductionOwing to their numerous applications in the industrial manufacturing process, the problem of heat and mass transfer in the boundary layers of a continuously moving semi-infinite flat plate has attracted the attention of researchers for the past three decades. Some of the application areas are hot rolling, study production, metal spinning, drawing plastic films, glass blowing, continuous casting of metals and spinning of fibers. Annealing and thinning of copper wire is another example. In all these cases, the quality of the final product depends on the rate of heat and mass transfer at the moving surface. By drawing the strips in an electrically conducting fluid subjected to a magnetic field the rate of cooling can be controlled and the final products of the desired characteristic might be achieved. Sakiadis [1] studied the boundary layer of viscous fluid on the continuous moving solid surface. Gribben [2] investigated the MHD boundary layer flow over a semi-infinite plate with an aligned magnetic field in the presence of pressure gradient. Free convection boundary layers and the study on a uniformly heated vertical plate was presented by Goldstein and Eckert [3]. Beard and Walters [4] proposed the two-dimensional boundary layer flow for an elastico-viscous fluid near a stagnation point. In the present years, the free convective flow of heat and mass transfer problems in the presence of magnetic field through a porous medium have attracted the attention of a number of research scholars because of their possible application in many branches of science and technology such as fibre and granular insulation, a geothermal system, etc. In engineering sciences, it finds many applications in MHD pumps, MHD bearing, MHD power generators, etc. The effects of free convection on stokes problem for a vertical plate under the action of transversely applied magnetic field with heat and mass transfer was discussed by Soundalgekar et al. [5]. Thermal diffusion and natural convection between inclined plates in a porous medium with MHD was analyzed by Raju et al. [6]. Ahmed [7] discovered the radiating fluid and an induced magnetic field over a porous vertical plate. Samira et al. [8] derived free convection MHD flow of an elastovisco...
