Abstract
This pagination is executed to exemplify flow features exhibited by viscous fluid between two coaxially rotated disks. Thermal analysis is performed by using Cattaneo-Christov heat flux theory. Porosity aspects are also taken in to account. Mathematically structured non-linear PDEs are transmuted into non-linear ODEs by employing Karman transformations. Afterwards, solution is heeded by applying implicit finite difference scheme renowned as Keller box method. Interpretation of flow controlling parameters on axial, tangential and radial components of velocity, thermal distribution is exhibited. Assurance of computed data is done by managing comparison for skin friction coefficients at walls of disks. From the attained outcomes it is addressed that the magnitude of axial and radial velocities diminishes at lower disk contrary to upper disk for intensifying magnitude of Reynold number. Increment in tangential component of velocity is also demonstrated for uplifts values of Reynold number. It is also concluded that thermal field decrements for increasing of Pr and thermal relaxation parameter. It is worthy to mention that shear drag coefficient at wall of lower disk decreases conversely to the wall shear coefficient magnitude at wall of upper disk.
Highlights
Rotational fluid flow generated by coaxial disks is one of the classical problems of fluid mechanics
Batchelor [3] validated that Karman transformation can be evenly used for fluid flow between two coaxial rotating disks
Interpretation of flow phenomenon between porous stationary disk and solid rotating disk was manipulated by Kumar et al [8]
Summary
Rotational fluid flow generated by coaxial disks is one of the classical problems of fluid mechanics. In recent years, it has become a popular research area and has persuaded researchers due to magnificent theoretical and practical significance in engineering and applied sciences. Inaugurated work on flow induced due to rotating disk is performed by Karman [1]. Batchelor [3] validated that Karman transformation can be evenly used for fluid flow between two coaxial rotating disks. Chapple and Stokes [5] elucidated the flow features of fluid between two coaxially rotated disks. Mellor et al [6] bestowed comprehensive treatment of fluid flow restricted between two coaxial infinite disks, one rotating, and other stationary. Elmaboud et al [12] discussed peristaltic flow induced by sinusoidal wave propagating with constant speed on the walls of two-dimensional infinite rotating channel by heeding semi-analytical solutions
