Reiner Rivlin fluid flow between rotatable stretching disks with Cattaneo Christov heat transport

Abstract

The study of Reiner-Rivlin fluid dynamics between rotatable stretching disks with Cattaneo Christov heat transport has several potential applications across various fields, such as polymer processing, biomedical engineering, material science, geophysical fluid dynamics, tribology, and chemical engineering. Coaxial rotation of disks is achieved by rotating lower and upper disks. A cylindrical polar configuration with rotational symmetry is applied to model the problem and then solved using the homotropy analysis method. The convergence rate of the solution is discussed, and results are validated for the special sub-case of the present study. Physical trends of axial velocity, tangential velocity, radial velocity, temperature, skin friction coefficients, and heat flux against the variations of involved parameters have been discussed graphically. The axial velocity is enhanced and tangential velocity is diminished with the progression of the Reiner Rivlin parameter and Reynolds number. A higher Reiner Rivlin parameter increases the material resistance to deformation. The temperature function is diminished with the reduction in heat flux with the progression of the Cattaneo Christov parameter.
