14.1 Introduction

Fluid flowing between the parallel disk configurations is considered an important research topic because of its wider appliances industrial implications like turbine engines, power generators, lubrication systems, hydrodynamical machines, and rotating wafers. Hussain and Xu [1] investigated the slip effects in bio-thermal squeezed non-Newtonian material flow confined by the two parallel disks. Lehel and Hona [2] obtained similar solutions for the viscous fluid flow between the two orthogonally moving permeable disks with injection at the surfaces of the disks. Thompson et al. [3] analyzed the flow that combined the rotation and squeezing of two coaxial parallel disks. Abbas et al. [4] addressed the rheological behavior of Casson fluid between the in-plane movement of parallel disks. Park [5] studied the kinematics of the radial flow squeezed by the parallel disks by using persistence-of-straining.

Energy is one of the most important necessities for the whole world. The energy demand has been fulfilled by fossil fuels, but their accessibility is decreasing day by day. Thus, the use of thermal solar systems as an alternate energy source is becoming more and more vital. Thermal solar systems produce useful ...
