“…When magnetorheological effects are taken into account, Pillai et al [41] offered a study of the steady flow of a magnetorheological fluid in an inclined channel over a porous bed with a decaying exponential permeability that depends on the depth of the porous bed, using the model K (y) = K 0 e -cy , proposed by Sinha and Chadda [42]. Narasimha Murthy and Feyen [43] studied the influence of the variable permeability on the two MHD basic flows in porous media, using the variable permeability model 2 , where K 0 is the permeability in the interior of the porous medium and h the porous layer thickness.…”

This article involves the study and analysis of the fully developed flow of a magnetorheological fluid through a non-isotropic porous medium under the effect of an external, uniform, and transversal magnetic field. Permeability is taken as an exponential distribution function of the transverse direction. The Darcy-Brinkman-Lapwood-Lorentz equation for the fluid flow in porous media has been used and solved under non-slip boundary conditions by Modified Homotopy Perturbation Method and the results validated by the Numerical Shooting Method. Finally, the analysis of results is made of the influence on the velocity, volumetric flow, and wall shear stress.

“…Here we present a different discussion than that of Wang [1], which is actually an extension of Malathy and Srinivas [2] approach to porous media with changed unsteady pressure gradient. Jagadeeswara Pillai et al [3] studied the aligned magnetic effects on a steady laminar, viscous, incompressible, conducting fluid under varying bed permeability and used the Darcy's law in the porous medium. Vajravelu et al [4] examined the unsteady flow of two immiscible conducting fluids between permeable beds of different permeabilities.…”

An analytical solution of the flow of a hydromagnetic fluid through a porous medium between permeable beds is obtained and studied. The fluid is under an exponential decaying pressure gradient and the uniform magnetic field in a direction normal to the flow saturated porous medium is considered. Two governing equations, namely Navier-Stokes equations and Darcy's law, are employed for the flow between and through the permeable beds, respectively. Injection and suction of the fluid through lower and upper permeable beds, respectively, with same velocity are allowed in the presence of porous medium and the uniform magnetic field. The velocity field and the volume flux are calculated analytically and presented graphically for different choices of the parameters exhibiting their phenomenal nature. Additionally if we replace the exponentially decaying pressure gradient by the pulsatile one and porousity of medium tends to zero, the results match excellently with those of Malathy and Srinivas [T. Malathy and S. Srinivas, Pulsatile flow of a hydromagnetic fluid between permeable beds, Int. Comm. In Heat and Mass Transfer 35, 681-688 (2008)].

The purpose of this article is to study the necessity of creation and road maps usage as an effective ‎tool in order to create novel approaches for managing innovative high-tech projects using the author-developed criterion of innovative ‎tension, interpreted as the difference of potentials of participants in the innovation process — the ‎donor-enterprise of innovations and the recipient-enterprise of innovations.‎ The method of comparative analysis of various forms of organization of the innovation process and the corresponding variants of the ‎ratio of innovative potentials of participating enterprises was used. As a result of the conducted research, methodical approaches to evaluate innovation potentials of donors-enterprises of innovations and enterprises-recipients of innovations were developed. A ‎criterion for estimating the innovative potential in the donor-recipient system, so-called innovative stress, is formulated. An attempt to disclose the importance of methodological support of road maps on the example of ‎innovative projects is made.
