【 摘 要 】

The present paper considers suction/injection, constant and variable thermophysical influence in squeezing flow of magnetized blood rheological (Casson) fluid model between two parallel disks subjected to nonlinear convection process, slip and convective surface conditions. The unsteady, squeezing, magnetized, and chemically reacting dissipative fluid flowing between parallel disks is modeled and non-dimensionalized via an applicable similarity transformation. An approximate solution of the flow distributions is sought by employing the Chebyshev Collocation Approach (CCA). In the limiting scenario, an excellent agreement in the present results with the existing literature is obtained. The analysis reveals the dominance of constant thermophysical effect over the variable thermo-properties on velocities and temperature field. Higher thermal/solutal Biot number highlighted the dominance of positive squeezing number while its minimal values showcase the dominance of negative squeezing number on flow and energy field. Therein, the squeezing effect remains invariant for some range values of thermal/solutal Biot number, while a rise in velocity slip and suction parameter enhanced the fluid velocities and concentration profiles respectively. Moreover, the current analysis is applicable in moving engines such as in parallel disk gate valve, locomotion of piston in ring where oil is viewed as Casson fluid, thermoforming, injection molding, biomedical use among others.
