“…Dhole et al [5] developed heat transfer correlations of forced convection past a sphere in the range of 56 < Re < 6200 and 0.76 < Pr < 6400. Similar correlations were developed for a horizontal slender cylinder by Datta et al [6], including effects of non-uniform slot injection and transverse curvature. Also, effects of viscous dissipation and varying Prandtl numbers on the resulting skinfriction and heat transfer coefficients were reported.…”

“…In fact, if we choose uniform suction or injection in a slot causes finite discontinuities at the leading and the trailing edges of the slot. Those discontinuities can be avoided by choosing non-uniform mass transfer in a slot and it was pointed out by many previous researchers (Riley, 1981;Saikrishnan, 2003, 2004;Saikrishnan and Roy, 2003;Datta et al, 2006).…”

“…Uniform suction or injection in a slot causes finite discontinuities at the leading and trailing edges of the slot which can be avoided by choosing a non-uniform suction or injection in a slot as discussed by Minkowycz et al (1988) and in an early work by Riley (1981) who considered non-uniform slot injection into a laminar boundary layer in both supersonic and subsonic flow. Recently, a few studies Saikrishnan, 2003, 2004;Saikrishnan and Roy, 2003;Datta et al, 2006;Ravindran and Ganapathirao, 2013;Ganapathirao et al, 2014;Samyuktha et al, 2016) reported non-uniform slot suction or injection into boundary layer flow past yawed cylinder, sphere, cone, rotating sphere, cylinder and plate.…”

In this investigation, our objective is to study the effect of non-uniform slot suction or injection into a steady mixed convective MHD boundary layer flow over a vertical wedge embedded in a porous medium in the presence of chemical reaction. The wall of the wedge is embedded in a uniform porous medium in order to allow possible fluid wall suction or injection. The surface of the wedge is maintained at a variable wall temperature and concentration. The fluid is assumed to be viscous, incompressible and electrically conducting; and the magnetic field is applied transversally in the direction of the flow. The governing boundary layer equations are transformed into a set of non-similar and non-dimensional equations by using suitable coordinate transformations. Non-similar solutions are obtained numerically by solving coupled non-linear partial differential equations using an implicit finite difference scheme in combination with the quasi-linearization technique. Comparisons with previously published works are performed and excellent agreement between the results is obtained. A parametric study of the physical parameters is conducted and a representative set of numerical results for the velocity, temperature and concentration distributions, as well as the local skin friction coefficient and the local Nusselt and Sherwood numbers are illustrated graphically to show interesting features of the solutions.

“…Various features of such problems have been studied by different researchers, for instance Hayat et al [8], Hayat et al [9], Xu and Liao [10], and Cortell [11,12]. Two dimensional boundary layer flow across a stretching cylinder was invoked by Datta et al [13]. Elabarbary [14] analyzed the heat transfer effects on micropolar across a stretching cylinder.…”

This work consists of a theoretical boundary layer analysis of heat and mass transport in a viscous fluid-embracing gyrotactic micro-organism over a cylinder. The flow governing equations are modeled through boundary layer approximations. The governing non-linear partial differential equations are lessened to a set of nonlinear ordinary differential equations using similitude transformation. The boundary layer equations are elucidated numerically, applying the spectral relaxation method with the aid of the computational software MATLAB. The impact of several pertinent parameters on flow convective characteristic phenomena are explored through the use of graphs and tables and are discussed with in-depth physical descriptions. In addition, the friction factor, the rate of heat transfer, rate of mass transfer, and the density number of the motile microorganism are also presented with respect to the above controlled parameters. It is noticed that for the increasing values of the magnetic parameter with reductions and enhancements, the density of the motile microorganism is a declining function of, and the concentration field enhances with the strengthening of, whereas it reduces with the rise of. Furthermore, the streamline patters are emphasized for the impact of controlled flow variables. Current outcomes are compared with the available results from previous cases and are observed to be in agreement.
