    Description: An exact solution for the steady state Navier-Stokes equations in cylindrical coordinates is presented in this work. It serves to investigate the fluid flow and heat transfer occurring between two stretchable disks rotating co-axially at constant distance apart. The governing equations of motion and energy are first transformed into a set of nonlinear differential equation system by the use of von Karman similarity transformations, which are later solved numerically. The small Reynolds number case allows us to extract closed-form solutions for the physical phenomenon. The effects of the same or opposite direction rotation, as well as the stretching parameter and the Reynolds number, are discussed on the flow and heat characteristics. The main physical implication of the results is that stretching action of a disk surface alters considerably the classical flow behavior occurring between two disks and the physically interesting quantities like the torque and heat transfer are elucidated in the presence of a new physical mechanism; that is the surface stretching in the current research.

    Description: This paper is concerned with the analysis of magnetohydrodynamic fluid flow and heat transfer due to two-three dimensional porous and deforming (stretching/shrinking) bodies. It is aimed to prove from a theoretical approach that several boundary value problems regardless of two or three dimensions associated with the stretching/shrinking surfaces having different physical origin result in either the equivalent structure of governing equations or the interchangeable role of mechanisms of stretching or shrinking. Therefore, a link is created between the deforming surface phenomena considered in different geometries in the open literature. On the grounds of the provided theorems, a special care must be paid before working on the variations of this physical phenomenon, since the skin friction and the rate of heat transfer of engineering interest may have already been extracted from an already studied twin problem, namely the two-dimensional nonlinear (power-law) deformation analysis. It is further shown that the radial nonlinear stretching/shrinking sheet problem also evolves into the two-dimensional nonlinear wall deformation problem.
