Abstract

Abstract: This paper explores the compressible dusty fluid flow between two spinning disks. The upper and lower disks rotate at an angular velocity equal to Ω 1 and Ω 2 respectively. Fluid and dust particles are considered to be dispersed axisymmetrically. The equations which represents the described flow are transformed into a set of ordinary differential equations which are nonlinear and coupled by opting suitable similarity variables. These equations are solved using the built-in bvp4c algorithm of MATLAB. The profiles of axial, radial, azimuthal velocity and thermal profiles are discussed through graphs for variations of non-dimensional parameters. It has been observed that the friction factor enhances with the upsurge in values of Hartmann number Ha and the Nusselt number declines for shoot up values of Eckert number. Also, the stretching parameter amplifies the friction factor and the Nusselt number.
